【摘要】 研究了钛酸盐陶瓷的晶体结构和性能,通过PCT实验测定了钛酸锶的浸出率。实验结果表明:钛酸盐陶瓷固化体具有较高的密度,浸出率低,化学稳定性高,是固化放射性废物和进行最终地质处置的理想固化体。展望了钛酸盐陶瓷固化放射性废物的前景。更多还原

【Abstract】 This paper investigated the crystal structure and property of t it anate ceramics. Its leaching property was characterized by PCT test method. The results show that the titanate ceramics has high density, low leaching rate and high stablility.It can be concluded that the titanate ceramics is a promising m aterial for immobilizing radioactive waste (RAW). It is expected to be used in s elf- propagating high- temperature synthesis of immobilizing radioactive waste .更多还原
