Calcium Phosphate Dental Materials Prodused with the Help of Natural Alumosilicates

Abstract

Calcium phosphates are well known to be perspective as biomaterials, for example. the dental ones. There are two tendencies in investigation and design of such materials. They are the search of porous biomaterials and development of dense bioceramics on the basic of hydroxópatite and crystallized calcium phosphate glasses. Control of glasses crystallization with the help of modificators and nucleating agents is the main way for producing dense biomaterials [1, 2]. We used natural alumosiiicates, for example, kaolin as a reagent and modificator for calcium polyphosphate to achieve a good quality of materials without stages of glass formation and glass crystallization.
