Cobalt oxide (Co203) is an expensive cobalt oxide with a theoretical cobalt content of 71.06%, an oxygen content of 28.94%, and a density of 6.079/cm3. It is a black amorphous powder that generates cobalt oxide (Co304) after heating. Cobalt oxide is an unstable compound and cannot be freed. The cobalt oxide commonly referred to actually still contains a certain amount of cobalt tetraoxide. Co203 is only stable in a hydrated state. This hydrate will dehydrate and transform into the intermediate oxide cobalt tetraoxide (Co304) at 265�°C. Cobalt oxide is reduced to cobalt tetraoxide (Co304) by H2 at 125�°C, reduced to CoO at 200�°C, and reduced to cobalt metal at 250�°C. Cobalt oxide is insoluble in water. After dissolving in water, it decomposes into hydrates when it encounters water. It is insoluble in water, but soluble in acid and forms corresponding salts.

COBALT METAL PIECE The development of cobalt In the case of cobalt, the ancient greeks and Romans used its compound to make colored glass to produce a beautiful dark blue.By the 20th century, cobalt and its alloys had been widely used in the electrical, mechanical, chemical, aerospace and other industrial sectors and had become an important strategic metal.China began to extract cobalt from cobalt ore, nickel ore and cobalt-bearing pyrite in the 1950s.The use of cobalt minerals has a long history. The egyptians used cobalt blue as a coloring agent for ceramic products in the BC period, and cobalt compounds have been widely used in ceramic production since the tang dynasty.Cobalt was first isolated by the Swedish chemist Brandt in 1735 and identified as an element by Bergman in 1780. The use of the cobalt At present, the consumption and application of cobalt in the traditional fields are mainly battery Cobalt materials, super heat resistant alloy, tool steel, carbide, magnetic materials;Cobalt, which is consumed as a compound, is mainly used as a catalyst, desiccant, reagent, pigment and dye.Cobalt-60 is a widely used radioactive material widely used in biochemistry for activation analysis.For tracer studies in electroplating, corrosion and catalysis;It is used in medicine for radiological examination and treatment.
Cobalt is a chemical element with symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal cobalt Oxlate cobalt sulphate Cobalt Chloride Cobalt Carbonate Cobalt Powder cobalt chevrolet cobalt hydroxide cobalt oxide cobalt ore cobalt nitrate cobalt wire cobalt bar cobalt blue cobalt fertilizer cobalt carbonate Origins: China,Canada,Russia,Australia,Zambia,Cuba,Philippines

Cobalt acetate is a moderately water soluble crystalline cobalt source That decomposes to cobalt oxide on heating. It is generally immediately Available in most volumes. All metallic acetates are inorganic salts containing A metal cation and the acetate anion, a univalent (-1 charge) polyatomic ion Composed of two carbon atoms ionically bound to three hydrogen and two Oxygen atoms (symbol: ch3coo) for a total formula weight of 59.05. Acetates are excellent precursors for production of ultra high purity compounds, Catalysts, and nanoscale materials.

Cobalt oxide is a consistent, reliable oxide and a common colorant in pottery. It is available in powdered form and is blackish in color. It is a very strong oxide, and using very small quantities yields bright, intense blues. In ceramics, cobalt oxide is used mainly in slips, washes and glazes and can be applied through brushwork, decals or other surface decorating techniques. It can also be added to porcelain or stoneware clay. Because cobalt oxide is not as finely powdered as cobalt carbonate, cobalt oxide is more likely to create blue specks, a quality that we believe can be quite beautiful! Because of the strength of this oxide as a colorant, glazes containing cobalt can produce halos and flashing during firings. [formula] Co3o4 [cas registry number] 1308-06-1 [synonyms] Cobalt oxide 73%, cobalt oxide frit grade. Black cobalt. Tricobalt tetraoxide. [appearance] Cobalt oxide occurs as a grey to black powder. [solubility] Cobalt oxide is insoluble in water but soluble in acids. [uses] Cobalt oxide is mainly used as a pigment for colouring glass and frits.

[classification] Cobalt oxide is hazardous to the environment and harmful, if swallowed; May cause sensitisation by skin contact and is toxic to aquatic organisms Causing long-term adverse effects in aquatic environment
Cobalt(ii) sulfate is any of the inorganic compounds with the formula coso4(h2o)6. Usually cobalt sulfate refers to the hydrate coso4.7h2o, which is one of the most commonly available salts of cobalt. [properties] Cobalt(ii) sulfate heptahydrate appears as red monoclinic crystals that liquify around 100 â°c and become anhydrous at 250 â°c. It is soluble in water, slightly soluble in ethanol, and especially soluble in methanol. The salts are paramagnetic. It forms by the reaction of metallic cobalt, its oxide, hydroxide, or carbonate with aqueous sulfuric acid.The hexahydrate is a metal aquo complex consisting of octahedral [co(h2o)6]2+ ions associated with sulfate anions.
