Crystal-Chemical Principles Underlying Monomineralic Composition Calculation for Glass-Ceramics

This paper presents a method of calculating and estimating the composition of starting mixtures for metasilicate glass-ceramics of a new class: Sikams. The method relies on crystal-chemical principles and takes into account isovalent and heterovalent isomorphism under directional solidification conditions. It ensures a high crystallization rate, a desired degree of structural and chemical homogeneity, and optimal physicochemical properties of the material, in which the crystalline component consists of pyroxene solid solutions. Moreover, it simplifies the fabrication process and reduces energy consumption.
