ABSTRACT:
This invention relates to the formation of a new solid material composed of calcium phosphates and to the reaction method for producing this material. The solid calcium phosphate material is created by chemically reacting calcium ion sources with phosphate ion sources in a molten state and cooling the reaction mixture to room temperature producing the solid material. Depending upon the ratio of components and the parameters of the heating reaction, the resulting material may be a smooth, non-porous material with exceptional hardness, or it may be a porous material. Both types of material can be shaped into desired configurations, such as artificial teeth.
