Hypercinnabar

This page is currently not sponsored. Click here to sponsor this page.
Formula:
HgS
Hardness:
3
Crystal System:
Hexagonal
Name:
In allusion to the fact that the stability field of the species extends to higher temperatures than that of cinnabar or metacinnabar.
Polymorph of:
The high-temperature phase of mercury sulphide, HgS. It shows a slight deficiency in Hg [Clark, 1993 - "Hey's Mineral Index"].
Structurally related to the Wurtzite Group.

Intimately associated with metacinnabar, which it generally resembles.
