Research ArticleOpen accessEvery word in the titleInfluence of Heat Treatment in Sintering Process on Characteristics of Al2o3-Zro2 Ceramics SystemsA. Rittidech, T. TunkasiriAl2O3-ZrO2 ceramics containing 5-50 mol% ZrO2 were prepared by solid state reaction method. The bulk density, average grain size and microhardness of Al2O3-ZrO2 ceramics system as function of ZrO2 content were investigated. The dense Al2O3-ZrO2 ceramics were successfully by means of carefully control processing parameters that include sintering temperature and heating/cooling rates. These ceramics with higher ZrO2 content was obtained … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,008 accessesView PDFCite
