PURPOSE:To manufacture the titled compound of stable quality useful as medical and dental materials in large quantities by irradiating Ca phosphate with laser light. CONSTITUTION:Ca phosphate such as Ca(HPO4)2.2H2O or CaHPO4.2H2O is irradiated with laser light having >=30J/cm<2> energy density. alpha-Ca3(PO4)2 of stable quality can be manufactured in large quantities as compared to a conventional heating method using an electric furnace. alpha-Ca3(PO4)2 is useful as medical and dental materials such as a packing material for root and a covering agent a medicine for pyorrhea alveolaris, a base for cement, an implanting material, a material for an artificial bone and a material for an artificial joint. |
