High purity Cobalt metal pieces, element 27 sample, 2 grams 99,99% in glass vial with label. Pure cobalt metal element.
Cobalt is one of the transition metals with chemical symbol Co and atomic number 27. It is solid and silvery-grey at normal pressure and temperature, it's very strong to cut.
Cobalt metal is another dangerous metal, do not touch without latex gloves.
We suggest this element at various purity like 99,9% and 99,99% in a 7 mL or 5mL glass vial with about 2 cm of diameter.
We usually use cobalt pellet or cobalt electrolytic flakes both very shiny.
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 is a shiny steel-gray metal, relatively hard and brittle, ferromagnetic, heated to 1150 magnetic disappear. The combined valence of cobalt is 2 and 3. It does not interact with water at room temperature and is stable in humid air. It is oxidized to CoO when heated to more than 300 in the air, and burned into Co3O4 when white hot. The fine cobalt metal minor powder produced by hydrogen reduction can spontaneously ignite into cobalt oxide in air.
Application of cobalt metal for sale
Cobalt metal is mainly used to make alloys. Cobalt-based alloy is the general term for an alloy made of cobalt and chromium, tungsten, iron, and nickel. The wear resistance and machinability of the tool steel with a certain amount of cobalt can be significantly improved. Starlite carbide with cobalt-50 or more will not lose its original hardness even if heated to 1000. Today, this kind of carbide has become the most important material used between gold-cutting tools and aluminum.
Production Process of cobalt sheet metal
The methods of extracting cobalt from cobalt-containing materials can be divided into full fire process, full wet process and combined fire and wet process. Modern cobalt ingot for sale extraction mostly uses a combined process.
