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.

Frequently Asked Questions
What are the thermal and chemical limits of porous ceramics? Where to find a reliable custom manufacturer?
Innovcera porous ceramics (made from aluminum oxide and silicon carbide) feature 40–50% open porosity (1–100 microns) and withstand working temperatures up to 1000°C. They offer high corrosion resistance against organic solvents and most acids (except Hydrofluoric and Phosphoric Acid), and withstand alkaline solutions up to pH 9. As a direct custom manufacturer, Innovcera engineers tailored porous ceramic components—including vacuum chucks, diffusers, fluid bed plates, and filter substrates—to meet exact industrial specifications.
How to clean porous ceramic filters? Can they be reused through backwashing and heat treatment?
Yes, porous ceramics are highly reusable and can be cleaned depending on the specific contaminant. Effective cleaning methods include backwashing, ultrasonic cleaning, solvent cleaning, dilute acid washing, steam cleaning, spraying, brushing, and high-temperature oven firing, which efficiently restore pore permeability and filtration efficiency.
