POROUS CERAMICS
Introductions
The range of Innovacera porous ceramic filters are 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 90 microns. Monolithic, single grade, aluminum
oxide porous ceramic is available in 6, 15, 30, 50, 60 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).
Silicon Carbide is more of a special order material, with a density of 1.9 g/cc, for more aggressive
applications and has a maximum operating temperature of 1800 F (1000 C) and has excellent thermal
shock resistance. These standard porous ceramic materials are naturally hydrophilic. For special
applications they maybe coated or impregnated to achieve a certain performance characteristic.
Specifically tailored techniques include:

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

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.
