| 1 | Preparation of titanium oxycarbide from various titanium raw materials:Part I.Carbothermal reduction显示文摘Carbothermal reduction was performed at temperatures up to 1600°C for vanadium-bearing titanomagnetite,ilmenite concentrate,and high titania slag.The possibility of selective carbothermal reduction was discussed in detail from the viewpoint of thermodynamics,and also tested.The products were analyzed by X-ray diffraction,scanning electron microscopy,and chemical analysis.The results show that it is possible to reduce all iron oxide to metallic iron,and titania to oxycarbide(TiCxOy),without the reduction of other oxides like silica and magnesia. | GAO Chengjun,JIANG Bo,CAO Zhanmin,HUANG Kai,and ZHU Hongmin School of Metallurgical and Ecological Engineering,University of Science and Technology Beijing,Beijing 100083,China | 2010 | Rare Metals2010，29，6： | 7 |
| 2 | Prediction of surface and interfacial tension based on thermodynamic data and CALPHAD approach显示文摘In this article, following a brief introduction concerning experimental measurements of surface and interfacial tensions, methods for calculating surface tension and surface segregation for binary, ternary, and multicomponent high-temperature melts based on Bulter’s original treatment [1] and on available physical properties and thermodynamic data, especially excess Gibbs free energies of bulk phase and surface phase versus temperature obtained from thermody- namic databases using the calculation of phase diagram (CALPHAD) approach, with special attention to the model pa- rameter β, have been described. In addition, the geometric models can be extended to predict surface tensions of multicom- ponent systems from those of sub-binary systems. For illustration, some calculated examples, including Pb-free soldering systems and phase-diagram evaluation of binary alloys in nanoparticle systems are given. On the basis of surface tensions of high-temperature melts, interfacial tensions between liquid alloy and molten slag as well as molten slag and molten matter can be calculated using the Girifalco-Good equation [2]. Modifications are suggested in the Nishizawa’s model [3] for esti- mation of interfacial tension in liquid metal (A)/ceramics (MX) systems so that the calculations can be carried out based on the sublattice model and thermodynamic data, without deliberately differentiating the phase of MX at high temperature. Fi- nally, the derivation of an approximate expression for predicting interfacial tension between the high-temperature multi- component melts, employing Becker’s model [4] in conjunction with Bulter’s equation and interfacial tension data of the simple systems is described, and some examples concerning pyrometallurgical systems are given for better understanding. | QIAO Zhiyu CAO Zhanmin Tanaka Toshihiro | 2006 | Rare Metals2006，25，5： | 3 |
| 3 | Surface Tension Calculation of Undercooled Alloys显示文摘Based on the Butler equation and extrapolated thermodynamic data of undercooled alloys from those of liquid stable alloys, a method for surface tension calculation of undercooled alloys is proposed. The surface tensions of liquid stable and undercooled Ni-Cu (xNi=0.42) and Ni-Fe (xNi=0.3 and 0.7) alloys are calculated using STCBE (Surface Tension Calculation based on Butler Equation) program. The agreement between calculated values and experimental dare is good enough, and the temperature dependence of the surface tension can be reasonable down to 150-200 K under the liquid temperature of the alloys. | Zhiyu Qiao, Lijun Yan, Zhanmin Cao, Guirong Liu (Department of Physical Chemistry, University of Science and Technology Beijing, Beijing 100083, China) | 2001 | Rare Metals2001，20，1： | 2 |
| 4 | Zeta Potential and Rheological Behavior of ULC Castables Matrix显示文摘Effects of starting materials and four dispersants(STP,SHP,FDN and FS60) on Zeta potential and rheological behavior of alumina based ULC castables matrix were investigated.The results show that:characteristics of silica fume and alumina cements play a very important role in Zeta potential and viscosity of suspensions of the castables matrix;the dispersants STP and SHP can change Zeta potential values of the matrix suspensions remarkably;the four dispersants can effectively improve the rheological properties of matrix suspensions.For the point of lower viscosity of the matrix suspensions,the suitable additions of the three dispersants(SHP,FDN and FS60) are about 0.2% while that of STP is about 0.3%. | XU Yuanchao WANG Zhanmin CAO Xiying | 2008 | China's Refractories2008，17，2： | 1 |
| 5 | Enhanced carbon solubility in solvent for SiC rapid solution growth:Thermodynamic evaluation of Cr-Ce-Si-C system显示文摘The carbon dissolution in solvent plays a key role in the process of solution growth route for SiC single crystal,which could determine the growth rate and quality of the products.However,the carbon dissolving ability of binary alloy solvent still needs to be improved.Here,we demonstrate the improved carbon dissolution and enlarged carbon supersaturation in Cr-Ce-Si ternary solvent,showing great potential for SiC solution growth.The phase relations of Cr-Ce-Si-C system were determined by using CALPHAD method based on thermodynamic parameters of CeCr_(2)Si_(2)C.It is indicated that the Cr-Ce-Si ternary solvent shows much larger carbon solubility in temperature range from 1700 to 2000℃compared to Cr-Si binary one,Furthermore,the carbon supersaturation in solvent is also significantly increased in low temperature range after the addition of Ce,leading to a rapid growth rate.Our work not only demonstrates the feasibility of adding Ce in the alloy solvent for rapid growth of SiC crystal,but also provides an example for investigating the C solubility in ternary solvent. | Lingling Guo Guobin Wang Jiawei Lin Zhongnan Guo Zesheng Zhang Hui Li Zhanmin Cao Wenxia Yuan | 2023 | Journal of Rare Earths2023，41，8： | 1 |

| 9 | Thermodynamic assessment of the Ni-Sb binary system显示文摘The Ni-Sb binary alloy system was thermodynamically assessed using CALPHAD approach in this article. Excess Gibbs energies of solution phases, liquid and fcc phases, were formulated using the Redlich-Kister expression. The intermediate phases were modeled by the sublattice model with (Ni,Va)0.5(Ni,Sb)0.25(Ni)0.25 for Ni3Sb_HT phase and (Ni,Va)0.3333(Sb)0.3333(Ni,Va)0.3333 for NiSb phase. The other phases including Ni3Sb, Ni7Sb3, and NiSb2 were treated as stoichiometric compound owing to their narrow composition ranges. Based on the reported ther-modynamic properties and phase diagram data, the thermodynamic parameters of these phases were optimized, and the obtained values can reproduce the available experimental data well. | CAO Zhanmin TAKAKU Yoshikazu OHNUMA Ikuo KAINUMA Ryosuke ZHU Hongmin ISHIDA Kiyohito | 2008 | Rare Metals2008，27，4： | 1 |

| 11 | Study on Mechanism of Explosive Spalling of ULC Castables During Rapid Drying显示文摘Inner vapor pressure and temperature of vulnerable explosive spalling positions in refractory castables during rapid drying were measured by embedding pressure transmitting pipes and thermocouples during casting. The measured vapor pressure, temperature, and tensile strength of the castables were analyzed and discussed. A hollow sphere shell model was used to analyze the stress induced by the vapor pressure based on the structure of refractory castables. The mechanism of refractory castables explosive spalling caused by vapor-induced pore split was proposed. By comparing the vapor-induced stress and the tensile strength of the castables,the explosive spalling mechanism was validated quantitatively. | WANG Zhanmin ZHAO Jin CAO Xiying YU Lingyan ZHANG Sanhua SHI Gan HUANG Yufei ZHU Zhu | 2015 | China's Refractories2015，24，4： | 0 |
| 12 | Effect of H_(2)O_(2) Addition on Anti-explosion Performance of p-Al_(2)O_(3) Bonded Corundum Castables显示文摘In order to improve the anti-explosion performance ofρ-Al_(2)O_(3) bonded corundum castables,H_(2)O_(2) was added(0,0.025%,0.050%,0.075%,0.100%and 0.125%,by mass)as the anti-explosion agent.After mixing and casting,specimens were prepared.Some specimens were cured at room temperature for 12 h and demoulded for the anti-explosion performance test at different temperatures(450,500,550,600,650,700,750 and 800℃);the other specimens were cured,dried and fired,and tested in terms of the apparent porosity,the density,the cold mechanical properties,the air permeability and the pore size distribution.The results show that:(1)with the increase of the H_(2)O_(2) addition,the anti-explosion performance of castables increases gradually,the average pore size increases gradually,and the density and the strength decrease gradually;(2)by comprehensive consideration,the appropriate addition of H_(2)O_(2) shall be within 0.075%. | WANG Huan WANG Zhanmin FENG Haixia CAO Yingnan LIU Jun XU Yingshun | 2023 | China's Refractories2023，32，1： | 0 |

| 14 | Effect of Al Addition on Properties of Al_2O_3-SiC-C Dry Ramming Mixes for BF Trough显示文摘Aluminium powders were introduced to Al2O3-SiC-C dry ramming mixes in order to improve sintering properties and oxidation resistance according to their service conditions and installation methods. Properties such as bulk density, porosity, modulus of rupture, crushing strength and hot modulus of rupture as a function of aluminium addition were investigated in the present work. The microstructure and thermodynamics for the heat treated specimens were also analyzed. The results show that as aluminium addition increasing, the bulk density of the specimen treated at 220 ℃ tends to decrease and the apparent porosity increases, the strength of the specimens treated at 1 100 ℃ and 1 450 ℃ increases markedly, the bulk density tends to increase, apparent porosity and linear shrinkage decrease. The HMOR at 1 400 ℃ is enhanced from 1.0 MPa to 3.5 MPa with 3% aluminium. Aluminium is served as sintering agent and anti-oxidant and it will react with CO and CO2 forming Al2O3, which is helpful to enhance the strength, densify the structure and improve the overall properties. | WANG Zhanmin WANG Qiang CAO Xiying | 2008 | China's Refractories2008，17，3： | 0 |
| 15 | Internal Stress of Dense Refractory Castables During Unilateral Heating显示文摘The change of the internal stress of dense refractory castables during unilateral rapid heating was studied by the electric stress measurement. The results indicate that:(1) during rapid heating,the position near the heated surface is under compressive stress; the closer the position to the heated surface,the larger the compressive stress;(2) the specimen bursts during the rapid heating;(3)the calculated stress of the structure at the burst moment shows that the compressive stress produced at the same depth as the cracking surface exceeds the ultimate strength of the structure. | zhang xin liu yan wang zhanmin cao xiying zhao jin lu zhiqiang | 2018 | China's Refractories2018，27，1： | 0 |
