About AschamalmiteHide

Specific Gravity:
7.33 (Calculated)
Crystal System:
For the type locality
Closely related to heyrovskýite.
Aschamalmite has a monoclinically distorted structure (due to Pb-Bi ordering), unlike heyrovskýite (orthorhombic). Aschamalmite is apparently only stable <350°C.

Classification of AschamalmiteHide


2 : SULFIDES and SULFOSALTS (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.)
J : Sulfosalts of PbS archetype
B : Galena derivatives, with Pb

1 : ø > 4

3 : Sulphides, Selenides, Tellurides, Arsenides and Bismuthides (except the arsenides, antimonides and bismuthides of Cu, Ag and Au, which are included in Section 1)
6 : Sulphides etc. of Sb and Pb
