They are as below:
1) Cobalt (II) oxide known as Cobaltous Oxide or Cobalt monoxide.
2) Cobalt (III) oxide known as the Cobaltic oxide or Dicobalt trioxide.
3) Cobalt (II, III) oxide known as Cobaltosic oxide, Tri Cobalt tetroxide, Cobalto-cobaltic oxide.
Cobalt (II) oxide CAS number [1307-96-6] has Molecular formula CoO, Mol. Wt.: 74.9326 gm. /mole. It is a blackish or grayish powder finds its application mainly in ceramic industries and also in chemical industries for preparing Cobalt (II) salts such as Cobalt (II) nitrate having Mol. Formula Co( NO3 )2.
Cobalt (III) oxide CAS number [1308-04-9] has Molecular formula Co2 O3, Mol. Wt.: 165.86 gm. / mole. It is a black colored powder.
Cobalt (II, III) oxide CAS number [1308-06-1] has Molecular formula Co3 O4, Molecular Wt.: 240.8 gm. /mole. It is available in black colored powder form, soluble in hot acids and alkali hydroxides. Cobalt (II, III) oxide is used mainly as a pigment in glass industries.

Cobalt oxide is an olive-green to red crystals or grayish or black powder in appearance, cobalt oxide is used extensively in the ceramics industry as an additive to create blue colored glazes and names as well as in the chemical industry for producing cobalt (II) salts.

Cobalt oxide is a metallic pigment that provides blue coloring in porcelains and glass. Various forms of cobalt oxide are changes to CoO at 850 – 900 C. CoO is a grayish brown powder that decomposes at 1935 C, insoluble in water. It is also used as a drying agent in inks and varnishes and as a feed and fertilizer additive.

Cobalt Chloride Powder refers most commonly to the inorganic compound with the formula CoCl2.6H2O, which when hydrated is the deep rose. Because of this dramatic color change and the ease of the hydration/dehydration reaction, “Cobalt Chloride” is used as an indicator for water in desiccants. The rose hexahydrate is one of the most common Cobalt chloride compounds in the laboratory. Cobalt chloride is mainly used for electroplating of cobalt and for the preparation of reagents used in organic synthesis.

cobalt chloride is widely used for hydration and dehydration reaction and other chemical synthesis processes

Cobalt (II) carbonate is the inorganic compound with the formula CoCO3. 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.

Cobalt Carbonate Powder, also known as spherocobaltite, is a mineral with chemical formula CoCO3. It is the carbonate salt of cobalt. It forms red trigonal crystals with specific gravity 4.13 which decompose on melting. Cobalt carbonate is insoluble in either cold or hot water but soluble in acids.
Cobalt carbonate is used in pottery glazes and may be found in pottery supply stores. Cobalt carbonate has same coloring application as it decomposes to cobalt oxide at high temperature. Cobalt carbonate tends to disperse better in a glaze but can produce blisters because of the CO2 gas presence at high temperature. Commercial grades of cobalt carbonate are the complex of carbonate and hydroxide such as cobalt carbonate

hydroxide (1:1) (CAS RN: 12069-68-0), Cobalt carbonate hydroxide (2:3) (CAS RN: 12602-23-2), and cobalt carbonate hydroxide (2:3) monohydrate (CAS RN: 51839-24-8).

Cobalt Nitrate Powder is a chemical salt formed from the metal cobalt and the nitrate ion. Cobalt nitrate is an oxidizer and is soluble in water. Cobalt nitrate is more commonly found as a hexahydrate, Co (NO3)2·6H2O. Cobalt nitrate is deliquescent in moist air and soluble in most polar solvents. It is derived from reacting metallic cobalt or one of its oxides, hydroxides, or carbonate with nitric acid. Cobalt nitrate is commonly used in dyes and inks.

The high solubility of cobalt nitrate makes it a common source of cobalt in metal-organic frameworks and polymers.
Cobalt (II) nitrate is a strong oxidant.
