XRD analysis of activated four-component ceramics

The aim of the presented research was to analyze ceramic material based on cordierite as a function of activation time and sintering temperature. Three-component oxide mixture was prepared (MgO + Al2O3 + SiO2 in the ratio 2:2:5). To decrease the sintering temperature, 10 mass % Bi2O3 was added to this mixture. The mixtures were mechanically activated for 5 and 240 minutes in a ceramic ball mill. Activated mixtures were sintered at temperatures of 1173-1573K. XRD method was used to determine the structural transformations of the obtained products.
