Filter disc

Product overview
Innovcera porous ceramic filters are manufactured from aluminum oxide (Al2O3) and silicon carbide (SiC). The material provides a uniform porous structure with 40–50% open porosity and tortuous pore channels. Pore sizes are available from 1 to 100 µm for controlled filtration, diffusion and gas/liquid distribution applications.

Materials & Structure
Constructed from Al2O3 and SiC, the porous bodies combine mechanical stability and well-defined interconnected porosity. The controlled pore distribution enables reproducible flow and particle retention characteristics across batches.

Maximum Temperature
Porous ceramic elements tolerate service temperatures up to 1000°C; actual limits depend on ancillary components such as sealants, gaskets and hardware.

Corrosion Resistance
Resistant to most acids (excluding hydrofluoric and phosphoric acid) and to many organic solvents. In alkaline media resistance is typically maintained up to pH 9. Note: compatibility of sealants, gaskets and fittings must be verified for specific fluids.

Cleanability
Cleaning method should be selected by contaminant type. Common methods include:

• Spraying
• Brushing
• Backwashing
• Oven firing
• Dilute acid cleaning
• Solvent cleaning
• Steam cleaning
• Ultrasonic cleaning

Typical uses

• 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

Applications
Used where a uniform, controlled pore size is required: chemical processing, semiconductor manufacturing, pharmaceutical processing and general industrial filtration or gas distribution tasks.
