Texture and fractal analysis of silica-alumina glass ceramics

Resumo

Using electron-microscopy micrographs, texture and fractal characteristics of the microstructure of silica-alumina glass ceramics are calculated at different temperatures. The relationship between the numerical characteristics of the intensity of liquation and crystallization processes of aluminosilicate glass ceramic samples and their thermal coefficients of linear expansion with the values of the fractal dimension and its derivatives is established for photomicrographs of the studied heat-treated samples.
