A-12 PREPARATION AND CHARACTERIZATION OF ALUMINA-ZIRCONIA SOLID SOLUTION POWDERS(Session: Ceramics III)
Details
Al_2O_3-ZrO_2 (AZ_x), with x=5, 15, 25, 35, 45 and 50 mol% ZrO_2 content, were prepared by Co-precipitation method. Synthesized powders were characterized thermal reaction by differential thermal analysis technique (TG-DTA) and were investigated phase formation using x-ray diffraction. It was indicated that the reaction was happened at temperature between 850℃ to 1100℃. AZ_x powders were successfully obtained for calcination conditions of 1000℃ for 2 h. Moreover, morphology and particle size evolution have been determined via SEM technique. It is showed that particles are agglomerated and basically irregular in shape.
