Porous Ceramics

Porous ceramics

Our range of porous ceramic filters is made of aluminum oxide and silicon carbide. This durable, uniform porous ceramic has an open porosity of 40-50% with a tortuous pore structure and is available in pore sizes from 1 to 100 microns.

Maximum temperature

Up to 1000C for porous ceramics, limited only by sealants, gaskets and/or fasteners.

Corrosion resistance

Porous ceramics are resistant to most acids, with the exception of hydrofluoric and phosphoric acids. In alkaline solutions, porous ceramics are stable up to pH 9. They are also resistant to organic solvents. Sealants, gaskets, and/or fasteners used may be a limiting factor for some fluids.

Cleanability

Porous ceramics can be cleaned using a variety of methods, depending on the type of contaminant being removed. These methods include spraying, brushing, backwashing, kiln firing, cleaning with dilute acid, 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
• Handling ceramic ash
• Ceramic absorbents
• Fluidized bed ceramic plates
• Ceramic special bubblers
• Ceramic breathers – Vents

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