High Quality CAS 12190-79-3 Cobalt Oxide for Lithium Battery Cathode Material
Lithium cobalt oxide, also known as lithium cobalt oxide, chemical formula LiCoO2, is an inorganic compound that is generally used as a positive electrode material for lithium-ion batteries. The structure of LiCoO2 has been studied by X-ray diffraction, electron microscopy and neutron powder diffraction. The lithium atomic layer lies between plates of regular octahedrons formed by cobalt and oxygen atoms (shown below). This structure is in agreement with the structure predicted by the theory. Lithium cobalt oxide is toxic and should be handled safely.

It is a cobalt-based alloy that is resistant to wear and corrosion. The first cobalt-based alloy was a cobalt-chromium binary alloy, which was later developed into a cobalt-chromium-tungsten ternary composition, and then later did the cobalt-chromium-molybdenum alloy develop. Cobalt-chromium-molybdenum alloy is a kind of alloy with cobalt as the main component, containing a considerable amount of chromium, molybdenum and a small amount of nickel, carbon and other alloying elements, and occasionally also containing iron.

Characteristic.
Cobalt powder is gray and irregular, soluble in acid, magnetic, easy to oxidize in wet air. It is widely used in aviation,
aerospace, electrical, mechanical manufacturing, chemical and ceramic industries. Cobalt based alloys or cobalt containing alloy steels are used as high temperature heat-resistant parts and important metal materials in atomic energy industry as blades, impeller, conduit, jet engine, rocket engine, missile component and chemical equipment of turbine.
As a binder in powder metallurgy, cobalt can ensure the toughness of the hard alloy. Magnetic alloys are indispensable materials in modern electronics and mechanical and electrical industries, which are used to make various components of sound, light, electricity and magnetic materials. Cobalt is also an important part of permanent magnetic alloys. In chemical industry, cobalt isused in high alloy and anticorrosive alloy, and also used in colored glass, pigment, enamel, catalyst and desiccant.

Cobalt Tetroxide is similar to ferroferric oxide, and can be approximately regarded as a compound formed by cobalt oxide (CoO) and cobalt oxide (Co2O3). 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, n itric acid and h ydrochloric acid at room temperature. When heated above 1200 C, it will decompose into cobaltous oxide. When it is strongly heated to 900C in a hydrogen flame, it is reduced to metal cobalt.
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.
