制备方法与用途

性质

硝酸铈为无色至浅红色的潮解结晶状，相对密度为4.37。熔点为96°C，易溶于水，其水溶液呈微酸性或中性。硝酸铈还能溶解于醇和丙酮。当加热至158°C时会失去三个结晶水，继续加热至200°C则会发生分解。

用途

硝酸铈可作为制备其他铈盐的原料、分析试剂、合成试剂、石油催化剂以及煤气灯纱罩添加剂等。

类别

氧化剂

毒性分级

中毒

急性毒性

• 口服：大鼠LD50为3154毫克/公斤
• 静脉注射：大鼠LD50为37毫克/公斤

爆炸物危险特性

与还原剂、硫磺、磷等物质混合，受热、撞击或摩擦时可能发生爆炸。

可燃性危险特性

硝酸铈与有机物、还原剂、易燃物（如硫磺、磷）混合后可燃烧，并释放有毒的氮氧化物烟雾。

储运特性

应存放在通风良好且干燥的库房内；轻装轻卸；避免与有机物、还原剂、硫磺和磷等易燃物混存。灭火时可用雾状水或砂土进行处理。
