摘要
分析了钛酸锶 (SrTiO3)的晶体结构和性能 ,利用自蔓延高温合成反应生成钛酸锶 (SrTiO3) ,使Sr2 + 直接参与合成反应 ,从根本上解决了Sr2 + 包容量的问题。通过多种现代分析技术研究了钛酸锶固化体的物理、化学性能。结果表明固化体样品密度高、孔隙率小、浸出率低且稳定性高 ,技术和经济上可行。
Strontium titanate samples were synthesized by self-propagating high-temperature synthesis (SHS). Sr^(2+) directly took part in the synthesis process. As a result, immobilization limitation issue is basically resolved. The strontium titanate were characterized by crystal structure, dense properties, leach rate, microstructure and scanning electron microscopy, and the synthesis process is feasible in technology and economy. It can be concluded that the strontium titanate is a perfect material to immobilize HLW.
