mercuric oxide

物化性质

外观与性状：

亮,橙色-红色或橙色-黄色粉末

密度：

11.14

熔点：

500ºC (dec.)

存储条件/存储方法：

库房通风低温干燥,与还原剂,酸类,食品分开储运

稳定性相关：

1.如果遵照规格使用和储存则不会分解

2.避免接触氧化物.吸入或与皮肤接触时极毒。有毒！

黄色或红色粉末，一般黄色氧化汞粒度在2μm以下，红色氧化汞多数为10～20μm，通过粉碎可以将红色氧化汞转化为黄色氧化汞。氧化汞存在两种结晶，分别属于六方晶系和单斜晶系。单斜晶系结晶是稳定的。相对密度11.1。在400℃以上，发生热分解生成汞蒸气。在水中溶解度极小，但在弱酸以外的酸中极易溶解。在氢气流中加热可还原成汞。可将SO₂氧化成SO₃。与过氧化氢反应生成过氧化汞。

其它信息：

1.性状：黄色或橙色重质粉末。见光缓慢变为暗黑色。加热变成红色，冷却后复至黄色。
