| 4 | Synthesis and formation mechanism of HfB_(2) ultrafine powders with low oxygen via flocculating settling assisted process and carbo/borothermal reduction显示文摘In this study,ultrafine HfB_(2) powders with low oxygen were synthesized by a flocculating settling process which yielded ceramic precursors and subsequent carbo/borothermal reduction of the precursors.The liquid phase precursor method can achieve uniform mixing of components at the molecular level through multiple complexation reactions,and then realize the carbo/borothermal reduction reaction at a lower temperature to obtain ultrapure HfB2 powders.The as-resulted quasi-spherical HfB2 powders under the optimum conditions(atomic molar ratio M:B:C=1:2.8:10)calcined at 1500°C for 1 h have an average particle size of 205 nm and an oxygen content of 0.097 wt.%.Detailed analysis of the phase evolution of precursors shows that the formation of HfB2 particles is a mass diffusion mode from the external to internal HfO_(2)cores.We reveal that below 1300°C,HfC is not an intermediate product of HfB2 powder during the transition of precursors.Instead,HfC was formed as a by-product at high temperatures in the carbo/borothermal reduction process.The proposed formation mechanism of HfB_(2) is completely different from the traditional two-step transformation method.After the sintering of the ultrafine powders,the HfB_(2) ceramics show a relative density of 96.1%and superior mechanical properties compared to other works.Furthermore,by simply replacing the initial metal source,chlorinated group IV and V transitional metals(Ti,Zr,Ta,Nb)can also convert into high-purity and ultrafine diborides.This work shows that flocculating settling assisted carbo/borothermal reduction has potential in lot size production of various high-purity and ultrafine boride powders. | Zhen Wang Yuan Cheng Kewei Li Tianxu Wang Mengen Hu Chunxue Zheng Xinyang Li Zhulin Huang Xiaoye Hu Yue Li Xinghong Zhang | 2023 | Journal of Materials Science & Technology2023，，33： | 0 |
| 5 | 6-37 A Method for Implementing Feedback Control of CSRe Dipolar Magnet Power Supply显示文摘The magnetic field created by dipolar magnet is very important for the quality of beam in CSRe. It is required that the magnetic fields fluctuation ranges less than 0.3 10??4 T. Unfortunately, results show that the magnetic fields fluctuate more widely than limited. Reasons for the fluctuation are complex, transfer drift over temperature,zero shift, and output stability of power supply can all lead to magnetic field fluctuation. It is impossible to eliminate the effects of these factors. One way to solve the problem is to make current compensation. | Gu Kewei Yuan Youjin Zhang Wei Wang Pengpeng | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 6 | Numerical Approximation of a Nonlinear 3D Heat Radiation Problem显示文摘In this paper,we are concerned with the numerical approximation of a steady-state heat radiation problem with a nonlinear Stefan-Boltzmann boundary condition in IR^(3).We first derive an equivalent minimization problem and then present a finite element analysis to the solution of such a minimization problem.Moreover,we apply the Newton iterative method for solving the nonlinear equation resulting from the minimization problem.A numerical example is given to illustrate theoretical results. | Liping Liu Min Huang Kewei Yuan Michal Křížek | 2009 | Advances in Applied Mathematics and Mechanics2009，1，1： | 0 |
