The composite ceramics comprises 10 to 30 mass % of a zirconia crystal phase including Ce-stabilized zirconia crystal particles which contain CeO2 in an amount of 9 to 12 ... 03/23/06 - 20060063661 - Alumina ceramic products The invention provides a sintered, yttria stabilized zirconium-toughened alumina ceramic product comprising about 80-94 w/w % Al2O3, about 5-19 w/w % ZrO2 and about 0.18-0.72 w/w % Y20. ... 12/08/05 - 20050272591 - Zro2-al2o3 composite ceramic material and production method therefor A ZrO2—Al2O3 composite ceramic material having excellent wear resistance, hardness, strength and toughness is provided. This ceramic material comprises a ZrO2 phase composed of 90 vol % or more of tetragonal ZrO2, and preferably containing 10 to 12 mol % of CeO2 as a stabilizer, and an Al2O3 phase. An ... 09/29/05 - 20050215416 - Method of reducing magnesium loss during sintering of aluminium oxide articles A method for reducing the loss of magnesium during the sintering of aluminum oxide articles, such as ceramic discharge vessels for lighting applications. Magnesium oxide is added to aluminum oxide articles to control grain growth during sintering, but the sintering causes magnesium loss from the article. In order to address ... 06/02/05 - 20050119107 - Alumina/zirconia ceramics and method of producing the same Composite ceramics having a high strength, a high toughness and an excellent abrasion resistance, and a method of producing the same. The composite ceramics comprises 10 to 30 mass % of a zirconia crystal phase containing 9 to 12 mol % of CeO2 and 2.8 to 4.5 mol % of ... ### FreshPatents.com Support |
