In order to obtain high strength β-tricalcium phosphate (β-TCP) ceramics, effect of alkali earth metals addition was investigated. Addition of magnesium increased the bending strength of the sintered β-TCP to 2010kgf/cm2. Formation of a solid solution by replacement of magnesium inhibited the phase transformation of β-TCP into α-TCP, and contracted the crystal lattice. The strengthening of β-TCP ceramics was assumed to be due to the generation of partial stresses in the sintered body by magnesium addition.
