Microstructure and Strength of Ceramics Prepared from Powders Synthesized Via Simultaneous and Sequential Deposition Routes

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.
