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 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

Sodium Hydroxide (Caustic Soda ) 98-99% Flakes.
Sodium Hydroxide, also known as lye and caustic soda, is an inorganic compound with formula NaOH. It is a white solid, a salt (ionic compound), consisting of sodium cations Na+ and hydroxide anions OHâ??. Sodium hydroxide is a highly caustic base and alkali, that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH·nH2O. The monohydrate NaOH·H2O cystallizes from water solutions between 12.3 and 61.8 C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound
Sodium Hydroxide Solution is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner.

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
