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
• Ceramic Filters
• Ceramic Diffusers
• Ceramic Air Bearings
• Ceramic Permeable Substrates
• Ceramic Dispersion Media
• Ceramic Ash Handling
• Ceramic Wicking Media
• Ceramic Fluidized Bed Plates
• Ceramic Specialty Spargers
• Ceramic Breathers – Vents

Porous ceramics are used where uniform controlled pore size is required in chemical process, semiconductor, pharmaceutical, and manufacturing applications.
