Calcium Aluminate/Refining Slag

Calcium aluminate is an inorganic salt with the chemical formula 3CaO·Al2O3. It is a white cubic crystal. Relative density 3.038, decomposes when heated to 1535°C. Insoluble in water, soluble in acid. It is commonly found as hexahydrate with a molecular weight of 377.96 and is a spherical colorless or white crystalline powder. Relative density 2.49, refractive index 1.605. It begins to dehydrate when heated to 250°C, begins to decompose and releases crystal water at 300°C, and decomposes at 700~800°C. It also decomposes when placed in water. It is prepared by reacting sodium aluminate with calcium chloride and calcium hydroxide. Used to make concrete accelerator
