补充资料:碳酸锰
   分子式  MnCO3
   分子量  114.95
   CAS号  598-62-9
  性质  玫瑰色三角晶系菱形晶体或无定形亮白棕色粉末。相对密度3.125。几乎不溶于水,微溶于含二氧化碳的水中。溶于稀无机酸,微溶于普通有机酸中,不溶于醇和液氨。在干燥空气中稳定。潮湿时易氧化,形成三氧化二锰而逐渐变为棕黑色,受热时分解放出二氧化碳。与水共沸时即水解。在沸腾的氢氧化钾中,生成氢氧化锰。
   用途  广泛用作脱硫的催化剂, 瓷釉颜料, 锰盐原料, 也用于肥料, 医药, 机械零件和磷化处理。
    毒性   参见金属锰。
   包装储运  用内衬聚乙烯塑料袋的木桶包装,每桶净重50kg。 应贮存阴凉、通风、干燥的库房中。应防止受潮、受热及变质。运输时要防雨淋和日晒。装卸时要轻拿轻放,防止包装破损。 失火时,可用水、砂土和灭火器扑救。
