Kiln shelves provide the flat surfaces necessary for supporting kiln ware, and they must remain clean and smooth to avoid glaze adhesion. Shelf wash should be applied regularly as this is the best way to do this. Shelves may be constructed using cordierite, high alumina or nitride-bonded silicon carbide materials; each type has their own… Continue reading kiln shelves

Silicon carbide is an incredibly versatile material, suitable for many different purposes. It is a semiconductor compound that can be doped with either n-type or p-type nitrogen, aluminum, or boron to achieve various effects. Silicon Carbide Burner Nozzle has an extremely low coefficient of thermal expansion and excellent thermal shock resistance. Furthermore, its sublimation capabilities… Continue reading Silicon Carbide Burner Nozzle

Hot pressing sintering of pure SiC powder can achieve densification, but it requires high temperature (>2000 °C) and high pressure (>35 MPa). Alliegro of Norton studied the effect of metal additives such as B, Al, Ni, Fe and Cr on the densification of sic ceramic, and proved that Al and Fe are the best additives… Continue reading hot pressing sintering silicon carbide ceramic
