Chemical Transformations of Calcium Phosphates during Production of Ceramic Materials on Their Basis

Abstract

Production of ceramic materials based on various calcium phosphates is a multistep process, which includes preparing a substance in a splintered state (powder or suspension), molding a sample or product using one of the available methods, and sintering. A given phase composition, microstructure, and shape of the sample are formed during sintering, which are properties necessary for the intended use of the material. All stages of the production of phosphate-based materials are performed, as a rule, by predetermined chemical reactions. The chemical transformations occurring at different stages of the production of ceramic materials based on calcium phosphates are examined in the present review.
