摘要：
Processes of thermal destruction and phase formation occuring in sol-gel compositions of the Al2O3-ZrO2-SiO2 system during heat treatment are investigated. It is shown that the most uniform phase composition is exhibited in the case of a 3-to-1 Al2O3-to-SiO2 ratio with 20 wt.% ZrO2 in the form of an oxynitrate salt.
