INNOVACERA | technical ceramic solutions

The range of Innovcera porous ceramic filters is 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 1 to 100 microns. Maximum Temperature Up to 1000C for porous ceramic, limited only by sealants, gaskets and/or hardware materials. Corrosion Resistance Porous ceramics are resistant to most acids, except for Hydrofluoric Acid and Phosphoric Acid. In alkaline solutions, porous ceramics are resistant up to pH9. It is also resistant to organic solvents. The sealants, gaskets and/or hardware materials used, may be the limiting factor in certain fluids. Cleanability Porous ceramic is cleanable by a variety of methods, depending on the type of contaminant to be removed. Methods include spraying, brushing, backwashing, oven firing, dilute acid cleaning, solvent cleaning, steam cleaning and ultrasonic cleaning. Porous ceramics are used for: Ceramic Vacuum Chucks Cera...

Innovacera have more than 7 years experience in producing  porous ceramic  part for vacuum chuck, filters, air bearings for semiconductor and pharmaceutical industry. The range of Innovacera porous ceramic filters is 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 1 to 100 microns. Monolithic, single grade, aluminum oxide porous ceramic is available in 6, 15, 30, 50, 60, and 100 microns pore sizes. The porous ceramic disc processing is not the same as other ceramics, such as alumina ceramic, zirconia ceramics because of its properties of pores, so when you process the porous ceramics disc, here are 4 points you need to pay attention to: Put the porous ceramic plate into the water for five minutes. Ensure the porous plate be full of water to avoid oil contamination permeate into pores. Cut the plate with the blade only, and then grind it with a gr...

Still, if glue is stuck, it can only be lower than 100 ° C. 3) Microporous ceramics generally do not mention the roughness problem, because there are micropores, but the surface smoothness is similar to Ra0.8 of dense ceramics. 4) Low thermal conductivity. Only dense materials will have high thermal conductivity. 5) Microporous ceramics cannot be used in a humid environment or come into contact with conductive liquids. Otherwi...
