Calcium Phosphate Ceramic Foam Obtained by Firing a Hydroxyapatite – Monocalcium Phosphate Monohydrate Powder Mixture

The introduction of 24 wt.% powder of monocalcium phosphate monohydrate after firing at 1200°C into an impregnating suspension based on hydroxyapatite powder heat-treated at 800°C effects the formation of calcium phosphate ceramic foam based on β-tricalcium phosphate and β-calcium pyrophosphate. Successive application of hydroxyapatite and biomimetic apatite to calcium phosphate ceramic foam effects greater strength and enrichment with α-tricalcium phosphate and hydroxyapatite. Multiphase calcium phosphate ceramic foam possesses porosity 35 – 60%, static strength to 0.08 MPa, and heightened bioactivity on account of the biomimetic apatite layer.
