What is the production of Chromium sulfide Cr2S3?

Chromium sulfur is a source of chromium that is acid-soluble, moderately water-soluble, and compatible with sulfates. Sulfate, also known as a sulfate ester, is formed when one or more hydrogens are replaced with a metal. Metallic sulfate is readily soluble and used to treat water. Fluorides and oxides are not soluble. Organometallics are soluble both in organic and water solutions.

Chromium sulfide can be produced by combining a stoichiometric amount of chromium powder with sulfur powder at a temperature of 1000degC.

The chromium-sulfur mixture can be obtained by mixing the two elements in a molar proportion of 2:3, heating in vacuum one day later, cooling and crushing, and finally heating in vacuum and cooling slowly.
