Abstract

Sol-gel techniques for simultaneous and sequential deposition of precursor powders for preparation of ceramics in the ZrO2 – Al2O3 – CeO2 system are described. The phase composition of ceramics varies with the method of powder deposition. The intracrystallite arrangement pattern of the secondary phase in the system obtained via simultaneous deposition route provides the base for a ceramic that is superior in strength characteristics to ceramic prepared from ZrO2 – Al2O3 powders deposited via sequential route.
