A porous ceramic is made from composite materials which consist of alumina and commercial rice husk ash. This type of ceramics is obtained by mixing the commercial rice husk ash as a source of silica (SiO2) and a pore forming agent with alumina (Al2O3) powder. To obtain this type of ceramic, a solid-state technique is used with sintering at high temperature
Ceramics tend to be weak in tension, but strong in compression. For a metal, the compressive strength is near that of the tensile strength, while for a ceramic, the compressive strength may be 10 times the tensile strength. Alumina, for example, has a tensile

Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000ºC or higher.
11.7 Ceramic Products Manufacturing 11.7.1 General1-3 Ceramics are defined as a class of inorganic, nonmetallic solids that are subjected to high temperature in manufacture and/or use. The most common ceramics are composed of oxides, carbides, and nitrides.
The final product is a ceramic material of composition SiC, in the form of fibers ranging in diameter from 10 to 15 m. By similar procedures, beginning with an appropriate organic polymer, ceramic fibers of other compositions such as boron nitride, BN, can be fabried.
The SiC whiskers-enhanced ceramic supports exhibited a porosity of 44.2% and an average pore size of 14.6 μm. Moreover, the samples also showed a gas permeability of 270 m3/m2·h·kPa, which is 1.7 times higher than that of the pristine SCPCs.
