ceramic has 40-50% open porosity with a tortuous pore structure and is available in pore sizes ranging from 1 to 120 microns.
Monolithic, single grade, aluminum oxide porous ceramic is available in 1, 15, 30, 50, 60, 80, 100 and 120 micron pore sizes.
Aluminum oxide is the most standard material, with a density of 2.2 g/cc, and has a maximum operating temperature of 1400 °F
(800 °C).
The range of porous ceramic products includes:
• Membrane and monolithic tubes
• Discs
• Plates and other components made from aluminum oxide and silicon carbide where tightly controlled pore size and porosity is
critical.

• Spraying
• Brushing
• Backwashing
• Oven firing
• Dilute acid cleaning
• Solvent cleaning plus steam
• Ultrasonic cleaning
