Stable up to 1,000C, Blasch can produce cordierite in a variety of shapes and a broad range of sizes to suit your application. Cordierite wall flow filters The most common filter is made of cordierite (a ceramic material that is also used as catalytic converter support. The porous SiC-cordierite ceramics were prepared from SiC, calcined kaolin, talc, aluminum hydroxide, and graphite as pore-forming. Therefore, in this study, hibonite [28,29] with excellent alkali corrosion resistance was compounded with cordierite, which has a low thermal expansion coefficient, to optimize the composition of the saggar. The excess MgO did not obviously reduce the crystallization temperature but increased the production of liquid and densification. Steatite and cordierite powders were separately synthesized from natural raw materials such as kaolinite and talc.
