Mercury(II) selenide Usage And Synthesis

Chemical Properties

gray powder(s); sublimes in vacuum [HAW93] [STR93]

Uses

Mercury(II) selenide is used in semiconductors, infrared detectors, solar cells, transistors and amplifiers. It is also used as filters in some steel plants in order to remove mercury from exhaust gases. Further, it is used as an ohmic contact to wide-gap II-VI semiconductors such as zinc selenide or zinc oxide.

Uses

Semiconductor in solar cells, thin-film transistors, infrared detectors, ultrasonic amplifiers.

Definition

Sublimes in a vacuum, d 8.266, insoluble in water.

Hazard

Highly toxic.
