01 / Technical dossier

The material. The evidence.

Reference properties and the analytical work needed to assess this material for industrial use.

TO-REF-CALCIUM-CHLORIDE

Revision 1.0 · Technical reference

Material identity

CaCl₂ (anhydrous); hydrates also occur

An industrial calcium salt, not automatically a mined mineral product. Specify anhydrous, dihydrate or other product form before evaluating an assay.

CAS 10043-52-4 · Anhydrous form

Malagasy provenance not verified

Industrial chemical reference. A Malagasy deposit, local production route and supplier provenance have not been verified. Not presented as a documented Madagascar mineral occurrence.
