Utilizing the character of silicon carbide and mullite,such as high temperature tolerance,great intensity,good heat conductivity,shock resisting,high thermal radiation,our company specializes in producing the new generation medium and high-grade silicon carbide and mullite products.They can not only reduce the capacity of kiln furniture,but also improve kiln loading capacity and products quality,and shorten the production circle.They distinguishes clearly from the other products both on appearance dimension and inner quality of products in the market at present.The products can endure long time without deforming,cracking,falling slag.They are especially used for high-grade sanitary ware and high quality ceramic products because of not polluting the color of the products.They are ideal materials for sanitary ware,domestic ceramic,electroceramics,grinding wheel,glass,chemical,cement,electricity industries etc.
