Cobalt(II) nitrate hexahydrate
class
brown-red crystals, deliquescent in moist air.
in the electrical engineering industry, for obtaining catalysts, in the production of driers, in analytical chemistry.
Cobalt compounds
Cobalt (Co) is part of various alloys and is used as a catalyst for the oxidation of NH3 in the production of HNO3, oil refining, and fat hydrogenation. Cobalt is obtained by sulfidizing roasting of any material containing Co. Initially, cobalt is converted into a solution and then separated from accompanying materials.
Properties of the reagent cobalt oxide
The chemical reagent cobalt oxide is obtained by calcining it without air access or by heating metallic cobalt in air. The appearance of the reagent: olive-green or brown crystals. They react with acids.

Cobalt sulfate Co is used as a pigment in the ceramic and glass industries. Cobalt sulfate is obtained by oxidizing cobalt sulfide in air.
Cobalt chloride Co is obtained by calcining powdered Co in a chlorine atmosphere or by dehydrating hydrates.
Cobalt stearate Co is used as an accelerator and drier in the production of polyester plastics. It is obtained by reacting Co salts with solutions of technical stearate salts or petroleum acids.
