  1. Adding sic can decreases sintering temperature of al2o3 efficaciously, but also can make the al2o3 crystal growth as flake, strengthen the coalescent of the al2o3 crystals, and the residual sic during sintering can strengthen the al2o3 ceramics. because the reaction between sic and al2o3 begins from the surface of samples, there is a compact protecting field on the surface of the samples to restrain o2 enter into the samples, and leave more pore in them to decrease the thermal expansion coefficient and increase their the al2o3 ceramics " thermal shock resistanc e times

    引入sic的樣品在燒結過程中,首先在樣品的表面產生sic與o _ 2及al _ 2o _ 3的反應,形成一層緻密的保護層,阻礙o _ 2進入材料內部,在材料的內部留下較大的氣孔率,可以降低其熱膨脹系數,並使材料在受熱過程中有一定的空間進行結構調整,能夠顯著的提高al _ 2o _ 3陶瓷材料的抗熱沖擊次數。
