Phosphoric Acid → Tricalcium Phosphate

Participants

Reaction Steps

CaCO3 and H3PO4 were mixed in such amounts that correspond to 47 mol % (26% by weight) of CaO and 53 mol % (74% by weight) of P2O5, respectively. The mixture was treated in the same manner as in Example 1 to obtain calcium phosphate type crystallizable glass. The glass was subjected to crystallizing treatment at 650° C. for 20 hours. The properties of the crystallized glass having an atomic ratio of Ca/P of 0.44 thereby obtained, are shown in Table 1.
