MANUFACTURE OF CALCIUM PHOSPHATE CAST BODY

PURPOSE:To manufacture a cast body having an optional form at comparative low temperature which is suitable for an artificial bone, artificial dental root and artificial crown or the like by casting calcium phosphate glass as a material. CONSTITUTION:Ca compound [for example, CaO, Ca(OH)2, CaCO3, et...

Zusammenfassung:	PURPOSE:To manufacture a cast body having an optional form at comparative low temperature which is suitable for an artificial bone, artificial dental root and artificial crown or the like by casting calcium phosphate glass as a material. CONSTITUTION:Ca compound [for example, CaO, Ca(OH)2, CaCO3, etc.] and phosphorus compound (for example, H3PO4, H4P2O7, etc.) are selected so that Ca/P (atomic ratio) is regulated to 0.35-1.7 and is melted at 900-1,600 deg.C and cast by using a mold preheated =10% degree of crystallization, the material which has 1.5-2 times mechanical strength per the glass cast body and is suitable, for example, for an artificial bone, artificial dental root and artificial crown or the like can be obtained.
