Carbide Ceramics - Fraunhofer IKTS
Silicon carbide is the most important material within the group of carbide ceramics, followed by boron, and titanium carbide. The coination of different carbides provides an additional possibility to realize special properties such as high electrical conductivity, high hardness, variable coefficients of thermal expansion and specific gliding properties.

Grinding Media Grinding media are the means used to crush or grind material in a mill. It comes in different forms such as alumina oxide balls, ceramic cylinders, or soda lime glass. At Norstone Inc., we offer all types of medias used for grinding, deagglomeration
Porous Silica Material | CoorsTek Corporation
The manufacture of porous silica material involves sintering molded blocks of powder, which is the same as that for conventional ceramics such as alumina and zirconia. With this method, known as gel casting, the raw material is mixed and suspended in liquid to form slurry which is poured into a mold to set.
Description: The range of Innovcera porous ceramic filters are made from aluminum oxide and silicon carbide. The strong, uniform porous ceramic has 40-50% open porosity with a tortuous pore structure and is available in pore sizes ranging from 6 to 90 microns.
