Dicalcium phosphate
Other Name :Calcium hydrogen phosphate Calcium phosphate,dibasic
Legal Number: CAS[7757-93-9] (anhydrous) CAS[7789-77-7] (dihydrate)
Molecular Formula: Anhydrous: CaHPO4; Dihydrate: CaHPO4·2H2O; 172.09
Relative Molecular Mass: Anhydrous: 136.06; Dihydrate: 172.09
Properties: White crystalline powder, odorless and tasteless, stable in air. Insoluble in water and ethanol, soluble in dilute hydrochloric acid, nitric acid and acetic acid. When heated above 75℃, it loses water and turns into anhydrous calcium phosphate; when strongly heated, it turns into calcium pyrophosphate.
