Cobalt carbonate, with a pink, rose red or light red crystalline powder appearance, partially in the form of hexagonal crystals with a density of about 4.13g/cm ³. When heated above 400 ℃, it decomposes into cobalt oxide, carbon dioxide and water, with stable chemical properties. It is insoluble in water and ethanol, difficult to dissolve in ammonia water, easily soluble in dilute acid and releases carbon dioxide. It reacts with strong alkaline solutions to produce cobalt hydroxide precipitate, exhibiting precise chemical response characteristics.

Indium is a white metal, extremely soft, extremely malleable and ductile. Cold weldability, and other metal friction can be attached, liquid indium excellent mobility. The metal indium is not oxidized by air at normal temperature, the indium starts to be oxidized at about 100℃, (At temperatures above 800 ℃), indium burns to form indium oxide, which has a blue-red flame. Indium is not obviously harmful to human body, but soluble compounds are toxic.

Cobalt Tetroxide is an inorganic compound with the chemical formula Co3O4,Black or grayish black powder. The apparent density is 0.5-1.5g/cm3, and the tap density is 2.0-3.0g/cm3. Cobalt Tetroxide can be slowly dissolved in hot sulfuric acid, but it is insoluble in water, nitric acid and hydrochloric acid at room temperature. When heated above 1200 ℃, it will decompose into cobaltous oxide. When it is strongly heated to 900℃ in a hydrogen flame, it is reduced to metal cobalt.
