| 简介 |
PURPOSE : A composition for high strength siliconoxycarbide bonded silicon carbide ceramics, high strength siliconoxycarbide bonded silicon carbide ceramics and a method of manufacturing the same are provided to reduce burning temperatures compared to using silicon carbide and burning time for energy efficiency and to have the excellence in the strength, intensity, fire resistance and uniformity of silicon carbide. CONSTITUTION : A composition for high strength siliconoxycarbide bonded silicon carbide ceramics comprises at least silicon carbide 70-90 by weight, polysiloxane 2.8-27 by weight, alkaline earth metal oxide 0.2-3 by weight and a material chosen from precursors of alkaline earth metal oxide by heating. The precursors of alkaline earth metal oxide by heating are carbide of alkaline earth metal oxide, nitride or alkoxide. The alkaline earth metal oxide is strontium oxide, calcium oxide or magnesium oxide. |
