Effect of Substitutional Monovalent and Divalent Metal Ions on Mechanical Properties of -Tricalcium Phosphate
-tricalcium phosphate (-TCP) powder doped with monovalent or divalent metal ions was hot pressed at 1100°C, and the effect of substitutional monovalent and divalent metal ions on mechanical properties of -TCP was investigated. The sinterability of -TCP would be enhanced by the substitution of monovalent and divalent metal ions for -TCP. Sintered -TCP doped with 7.6 mol% of Mg2+ ion showed a bending strength of 160 MPa. It was found that the substituition of Mg2+ ion up to 9.6 mol% and a small amount of monovalent metal ions for -TCP is effective to improve the mechanical strength of -TCP.
