The cobalt-containing waste material method is to react the cobalt-containing waste material with hydrochloric acid and sulfuric acid, convert it with sodium sulfide, and obtain it through washing, oxidation, separation, acidizing, washing, refining and concentrating.Ī preparation method of high-grade pure cobalt chloride, the steps of which are as follows:ġ) reaction of metallic cobalt with hydrochloric acid: the metallic cobalt is placed in a glass beaker, and add hydrochloric acid into the electric furnace for heating reaction, the reaction temperature is controlled at 70 ℃-75 ℃, and the appropriate amount of nitric acid is added to promote the complete dissolution of metal cobalt, the amount of hydrochloric acid is controlled at 15-20% of the amount of hydrochloric acid. The gas phase co-reduction with other metal halides under the action of hydrogen to form finely divided intermetallic compounds, which can be used as structural materials or have useful thermoelectric properties, magnetic and antioxidant compounds.Ĭobalt chloride is mainly prepared by metal cobalt method and cobalt-containing waste method, metal cobalt method is the reaction of metal cobalt with hydrochloric acid and nitric acid, after purification, precipitation, filtration, evaporation, crystallization and separation. Used as analytical reagents and ammonia absorbents It is also used as an absorbent for ammonia. Split chemistry is used for drop analysis of zinc, haploid breeding, in addition, it is also used to make hidden ink, cobalt chloride test paper (blue when dry, turn to pink when wet), color change silica gel, etc. Used as a catalyst in chemical reactions. The defense industry is used to make gas masks. The brewing industry is used as a stabilizer for beer foam. In animal husbandry for the configuration of compound feed. The coating industry is used in the manufacture of paint drying agents. The ceramic industry is used as a colorant. Information provided by: (external link)Ĭobalt chloride is mainly used for the preparation of cobalt oxide and metallic cobalt, as an electronic material of alloy material, A small amount is used in the manufacture of instruments for the production of barometers, hydrometers, dry and wet indicators, etc. Information provided by: (external link)
