The maximum substitution of monovalent, divalent, and trivalent metal ions for β‐tricalcium phosphate (β‐TCP) was investigated, and a substitution model of these metal ions for β‐TCP was proposed. Monovalent metal ions (M I ) could replace Ca(4) site and vacancy ( V Ca(4) ) in β‐TCP as 2M I =Ca 2+ + V Ca(4) and the maximum substitution was about 9.1 mol%. In the case of divalent metal ions (M II ), Ca(4) and Ca(5) sites were replaced by divalent metal ions as M II =Ca 2+ , and the maximum substitution was about 13.6 mol%. Trivalent metal ions (M III ) could be substituted for Ca(4) site and vacancy as 3M III =2Ca 2+ + V Ca(4) , and the maximum substitution was about 9.1 mol%.
