Description and Uses

Chromous chloride is a white-to-blue solid orlustrous needles which turn blue in water. Molecularweight =122.90; Boiling point =1300℃; Meltingpoint =824℃. Hazard Identification (based on NFPA-704M Rating System): Health 1, Flammability 0, Reactivity 0.Soluble in water.

The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties.
