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.
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.
Application
-Water atomized cobalt powder has a relatively coarse grain size, which can be used in welding materials to improve its toughness, impact resistance and wear resistance.
-Reduced cobalt powder is in fine size and high purity, can be widely used in diamond tools, powder metallurgy,

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

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.
Carbonate of cobalt, cobaltous carbonate, carbonicacid,
Cobalt(ii) carbonate, spherocobaltite.
[appearance]
Cobalt carbonate is an odorless purple powder.
[solubility]
Cobalt carbonate is insoluble in water and ammonia; but however soluble in acids.
[uses]
Cobalt carbonate is used as a microelement in the zootechnical industry,
As raw material in the production of pigments and as catalysts.
[description]
Cobalt carbonate is the inorganic compound with the formula coco3,
It is the carbonate salt of cobalt.
Cobalt carbonate is prepared by heating cobaltous sulfate with a solution of sodium bicarbonate.
This reddish paramagnetic solid is an intermediate in the hydrometallurgical purification of cobalt
From its ores. It is an inorganic pigment, and a precursor to catalysts.
[classification]
Cobalt carbonate is harmful if swallowed and may cause sensitisation by inhalation and skin contact
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.
Cobalt oxide is insoluble in water but soluble in acids.
[uses]
Cobalt oxide is mainly used as a pigment for colouring glass and frits.
Sometimes also used as catalyst or as a source for metallic cobalt.
[description]
Cobalt oxide is a is a harmful allergenic compound.
It is an inorganic compound and mostly found as tricobalt tetraoxide.
At room temperature is presented as a black odourless solid.
[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.
[uses]
Hydrated cobalt(ii) sulfate is used in the preparation of pigments, as well as in the manufacture of other cobalt salts. Cobalt pigment is used in porcelains and glass. Cobalt(ii) sulfate is used in storage batteries
And electroplating baths, sympathetic inks, and as an additive to soils and animal feeds. For these purposes, the cobalt sulfate is produced by treating cobalt oxide with sulfuric acid
