Glass crystal matt coatings in the system Na2O - B2O3 - ZnO - TiО2 - SiО2

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.
