The study indicated that using 0.05 … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 19 Jul 2013 · 7,966 accessesView PDFCite
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
Research ArticleOpen accessIn the keywordsEffect of Y2O3 Additions on Microstructure and Properties of Alumina–Magnesia CeramicsAurawan Rittidech, Pimpun Wisuwan, Thitima PinkhunthodThe purposes of this research are to prepare and investigate the characterization of 0.7MgO-xY2O3-(99.3-x)Al2O3 by varies x at 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0 wt% (AMY). AMY samples were synthesized by solid state reaction under two different sintering methods conventional sintering method (NS) and two stage sintering method (TS). Ceramic samples were sintered by conventional sintering at 1600°C for … …American Journal of Applied Sciences, Vol. 15, Issue 8 · 30 Oct 2018 · 8,029 accessesView PDFCite
