Brushite and monetite powders were hardened by hydration in the presence of a “solid pH buffer”. The hardening was accompanied by the transformation of the starting calcium phosphates into carbonate-containing hydroxyapatite and/or octacalcium phosphate. The resulting hardened bodies had porosities of 71-81% and diametral tensile strengths of 0.1-1.5MPa. Microstructures of the hardened bodies showed that the hardening was caused by the entanglement of microcrystals.
