高硅玻璃陶瓷对模拟高放废液中锕系核素的固化性能测试

摘要

为了提高玻璃固化体性能，将玻璃质的SiO2在1200℃条件下烧结制备成高硅玻璃陶瓷固化体。测试结果表明：高硅玻璃陶瓷固化体的密度、包容量及浸出率等性能均优于硼硅酸盐玻璃固化体。%High silica glass ceramic solidification was synthesized by sintering the vitreous silica at 1 200 ℃in order to improve the performance of the glass immobilization .The testing results show that the properties of high silica glass ceramic solidification ,for example ,density ,encapsulated capacity ,the leaching rate and so on ,are superior to the borosilicate glass immobilization .
