1磷酸盐玻璃固化体化学耐蚀性研究显示文摘以在美国Washington州Hanford市存放的17类不同组成的高放射性核废料(highlevelradioactivenuclearwaste,HLW)为研究对象,设计了含Cr2O3为4%(质量分数,下同)的模拟HLW。采用25%~35%磷酸盐与含Cr2O3的65%~75%的HLW模拟组成相混合,经1150~1250℃加热处理数小时,能熔化成为均质玻璃体,然后冷却成固化体。用试样坚固法(productconsistencytest,PCT)测试包容70%和75%HLW的2种玻璃固化体的各元素,在90℃放置7d,元素沥析量总和分别为小于1.5g/m2和2.0g/m2。用蒸汽水化侵蚀法(vaporhydrationtest,VHT)对此2种试样在200℃的水蒸汽中进行水化侵蚀,经7d处理,平均被侵蚀的速率分别小于0.2g/(m2·d)和3.5g/(m2·d)。晶化处理后的此2种试样的PCT和VHT测试结果与晶化前基本相近。对HLW不同包容量的玻璃固化体的红外光谱分析表明:在较高的HLW包容量的玻璃固化体的结构中,容易被水化的(PO3)-结构转化为分离的(P2O7)4-或(PO4)3-。X射线衍射分析表明:玻璃固化体中分离的(P2O7)4-和(PO4)3-阴离子团被金属离子Al3+,Fe3+,Cr3+和Zr4+等所连接,形成O—Me—O—P键,不仅提高了玻璃的抗析晶的能力,而且也大大地提高了其化学稳定性。样品O/(Si+P)的摩尔比为3.7~4.1,从结构上也表明核废料包容量高达70%~75%的玻璃固化体有优良的?黄文旵 周萘 DAY D E RAY C S 2004硅酸盐学报2004,32,4:6
2Synthesis, Crystal Structure and Calculated β Value of a Tetrahedral Zinc (II) Complex——Zn(2-NH_2py)_2Br_2显示文摘A new zinc(II) complex, Zn(2-NH2py)2Br2 (py=pyridine), has been synthesized, and its molecular structure has been confirmed by IR, elemental analysis and -ray crystal structure analysis. Its space group is P21/n with Mr=413.43 (C10H12Br2N4Zn), a=7.435(2), b=12.865(3), c=14.186(4)? b=94.08(2)? V=1353.5(5) 3, Z=4, Dc=2.029 g/cm3, F(000)=328, ?2.378mm-1, R=0.0283, wR=0.0501. The total observed reflections with I≥2?I) were 5314, of which the independent reflections were 3106. The complex structure contains a distorted tetrahedron formed by four atoms coordinated to zinc atom, namely two bromide atoms and two nitrogen atoms. The two ZnBr bond lengths within one molecule, 2.3763(6) and 2.4002(5)? respectively, are not equal; and so are the two ZnN bond lengths, which are 2.031(2) and 2.044(2)?respectively. The calculation results using PM3 method through MOPAC software package in Chem 3D show that its first molecular hyperpolarizability b value is 5.210-30esu, which is comparable with that of p-nitroaniline. No bulk SHG effect has been detected due to the centrosymmetric space group.REN Peng a SU Nan-Bing a QIN Jin-Gui a Michael W.
