    Mullite - cordierite kiln furniture is made of mullite, cordierite and other raw materials through the scientific compounding, high pressure vacuum extrusion molding, pressing, rolling, etc after high temperature firing of composite materials. Make full use of the mullite high temperature resistant performance is good and the characteristics of cordierite low thermal expansion coefficient, good thermal shock resistance and high temperature creep, is the most ideal for 1300 degrees of refractory products. Due to the ceramic product diversification, different, sintering temperature, sintering conditions, firing cycle, bearing and so on are also different, emerging company research and development of different type of high performance refractory kiln furniture can completely satisfy the requirement of the ceramic industry and other high temperature industries use.

    The following brand technical data measured data for the emerging company, we keep product upgrades, data update and not informed in advance. Professional achievements in quality, science and technology leading the future, emerging company will according to your conditions of use to provide you with the most suitable for your product.
