Ceramic Porous Membrane

High requirements are set to each porous ceramic membrane.

Ceramic porous membrane.

An example of a highly porous membrane is the type made of silicon carbide. Porous ceramic membranes can be used for the separation of oil and water solids and liquids and dusts in gas thallus or yeast blood cells and the clarification of alcohol in the chemical medical and food industries 42. With the development of technology lowering the cost of ceramic membranes and prepare membranes with high permeability high. Porous ceramic membranes with their various advantages such as better thermal chemical and mechanical resistance controllable micro structure and little pollution to our environment have been attracting much attention in the scientific community recently.

The porous supports are produced under extremely high temperatures up to 1 800 c as to assure stability and resistance to corrosive liquids. An example of an amorphous membrane is the silica membrane. The possibility of a molecular sieve amorphous sic ceramic membrane was first demonstrated for a polysilastyrene derived composite membrane on a porous vycor glass 320. Porous ceramic membranes are chiefly used for gas separation and micro or nanofiltration.

Amorphous silicon carbide ceramic membranes were prepared by thermal 317 e beam 321 or chemical 322 curing of pcss followed by pyrolysis in inert atmosphere. The ceramic flat membrane is a new type of high temperature plate porous ceramic membrane which is prepared by high temperature sintering process using inorganic materials such as alumina. They can be made from both crystalline as well as amorphous solids.
