The features of the crystallization process of calcium-phosphate glass powders with a particle size of 90 - 400 ?m have been investigated, the structure and phase composition of crystallized materials have been determined, and the sintering mode of narrow powder fractions has been optimized to obtain the maximum possible open porosity. The porosity of the sintered glass-crystalline materials is 25%, the pore size is about 100 microns. The obtained materials release calcium cations and phosphate anions into the aquatic environment, which is the key to their successful adaptation in the environment of a living organism.

The dependence of the crystallization ability of model glasses under conditions of firing coatings made of them on their thermal prehistory is revealed, and the mechanism for obtaining coatings with different degrees of gloss under conditions of directional crystallization is established. General regularities and features of phase transformations in glasses of the Na 2 O - B 2 O 3 - ZnO - TiO 2 - SiO 2 , which allow you to control the crystallization process and design glass-crystalline matte coatings with specified physicochemical and technological properties. Il. 2, bibliography: 6 titles.
