Chlorocalcite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
KCaCl3
Colour:
White, violet tinged
Hardness:
2½ - 3
Crystal System:
Orthorhombic
Name:
In allusion to the composition, containing both CHLORine and CALCium.
Isostructural with:
The Ca analogue of javorieite.

Note: possibly isostructural with javorieite (if the synthetic KCaCl3 analogue is indeed structurally identical to chlorocalcite).
