制备方法与用途

简介

三氧化铼或氧化铼(VI)，化学式为ReO₃，是一种带有金属光泽的红色固体。它是VIIB族元素中唯一稳定的三氧化物。

性质

相较于一般氧化物，三氧化铼的电阻率不寻常地低，与金属相似，其电阻率随温度降低而下降。在300 K时，其电阻率为100.0 nΩ·m；而在100 K时，则降至6.0 nΩ·m。三氧化铼化学性质稳定，不易溶解于水、稀盐酸和稀氢氧化钠中，但能溶于浓硝酸转化为高铼酸。遇强碱会歧化反应，并在水中不存在铼(VI)酸盐。真空中加热至300℃以上时，三氧化铼会分解为Re₂O₇ 和 ReO₂。

制备

三氧化铼不能直接从元素制备，可通过CO在300℃下还原七氧化二铼获得：

[ \text{Re}_2\text{O}_7 + \text{CO} \rightarrow 2\text{ReO}_3 + \text{CO}_2 ]
