Cobalt Aluminate Powder Description
Cobalt Aluminate Powder is a kind of blue powder with a molecular formula of CoAl2O4 and a molecular weight of 176.89. It is insoluble in water and ethanol with a melting point of 1700 ~ 1800℃ and a relative density of 4.3718. Cobalt aluminate is known for its vibrant blue color, often referred to as "Cobalt Blue." This makes it a popular pigment in ceramics, paints, and glass. It can be obtained by heating a mixture of cobalt oxide, aluminum oxide, and potassium chloride, or heating a 1:2 mixture of cobalt nitrate and aluminum nitrate.
