制备

1.在隔绝空气的条件下，将HgCl2的稀溶液滴加到饱和的H2Se水溶液中，可得到HgSe沉淀产物。注意HgCl2不可过量，并且不可使用高浓度的HgCl2溶液，否则会形成HgCl2·2HgSe沉淀。

2.按化学计量比将HgCl2加入到强氨性的NaCN溶液中，然后加入等物质量的SeO2。该混合溶液经过滤后，通入SO2气体。在整个反应过程中，要保持溶液的碱性，以防止红色的硒沉淀析出。反应的终点，可通过SO2被吸收的速率下降来确定。反应结束后，将黑色的HgSe抽滤，并用含氨的稀NaCN溶液洗涤，接着用蒸馏水清洗，最后在盛有P2O5的干燥器内干燥。

3.按化学计量比将Hg和Se放入密闭的高压容器内，在550～600℃的温度下进行反应，然后将产物在600～650℃的纯N2气流中升华提纯，便可得到纯的HgSe产品。
