| 摘 要： | 熔制了模拟铯废物钛硅酸盐玻璃，用IR研究了玻璃的结构，用产品一致性试验法（PCT）研究了玻璃的化学稳定性，结果表明，所选组成的配料可以在1100℃熔制得玻璃，样品的密度在3．2703．35g/cm^3之间，玻璃中Ti^4 可能以[TiO4]进入玻璃网络，玻璃的结构主要由[SiO4]和[TiO4]组成，产品一致性试验法（PC）实验的浸出液中主要有R＋离子，当配料中n(TiO2):n(SiO2)为0．40－0．35时，浸出液中各种离子的浓度均较低，表明玻璃具有较好的化学稳定性。

| Abstract: | Titanosilicate glasses containing simulated cesium_loaded high level waste(HLW) of different molar ratio of TiO 2/SiO 2 were prepared. The IR method was used to study the structure of the glass. The product consistency test (PTC) method was used to study the chemical durability of the samples. The results show that in titanosilicate glasses Ti 4+ is in the form of . The chemical durability depends on TiO 2/SiO 2 molar ratio in the glasses and a good chemical durability with TiO 2/SiO 2 molar ratio of 0.35-0.40 was observed. |
