Porous α al 2 o 3 ceramic carriers are widely used in industrial ethylene epoxidation reactions and silver catalysts prepared by supporting silver particles on α al 2 o 3 carriers are the only catalyst in the field 30 31.
Porous ceramic particles.
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.
An improved porous ceramic article and a method for forming such porous ceramic article.
Pore ceramic structure can be designed using the size and morphology of the hydroxyapatite particles that are utilized to build these porous ceramics.
The article is formed by pressing slip casting extruding or injection molding the mixture.
The distinguished feature is that the construction of the porous structure stems from.
Porous hydroxyapatite ceramic exhibits strong joining to the bone the pores provide a strong mechanical interlock leading to a firmer fixation of the structure.
A mixture of ceramic particles and pliable organic hollow spheres is prepared in a liquid typically as a suspension.
In addition these membranes can act as biological reactors in the recovery of fermented liquid.
The article is dried to remove the liquid and then is fired so that the ceramic particles are.
