N2 - The preparation and strength of a calcium phosphate based cement with and without dispersed particles of polycrystalline 12 mol-%CeO2 doped tetragonal zirconia (12Ce-TZP) were investigated. A cement mixture of α-tricalcium phosphate (α-Ca3(PO4)2) and tetracalcium phosphate (Ca4(PO4)2O) with a Ca/P ratio of 1·67 transformed completely to hydroxyapatite after curing under water for 7 d at 38 °C. The compressive strength of a cement without dispersed 12Ce-TZP particles cured for 4 d at 38 °C was approximately 11·1 MPa but increased to approximately 16 MPa by dispersing 3 wt-%12Ce-TZP particles, of average diameter 40 μm, which were treated in 10 M NaOH and/or 0·01 M Ca5(PO4)2 gel solutions prior to dispersion.
