【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.更多还原
