| | 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. |
