    OverviewPreparationStructureUses and occurrenceSee also

    Dibasic calcium phosphate is produced by the neutralization of calcium hydroxide with phosphoric acid, which precipitates the dihydrate as a solid. At 60 °C the anhydrous form is precipitated: H3PO4 + Ca(OH)2 → CaHPO4To prevent degradation that would form hydroxyapatite, sodium pyrophosphate or trimagnesium phosphate octahydrateare added when for example, dibasic calcium phosphate dihydrate is to be used as a polish
