Product Description

Alumina Sic Zirconia Ceramic Foam Filter for Ion Alloy Metal Casting

Foam Ceramic are mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses . With their excellent thermal shock resistance and corrosion resistance from molten aluminum, they can effectively eliminate inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

Features
Ceramic foam is a new industrial ceramic products with low bulk density (0.25 ~ 0.65) g/cm³, high porosity (60% ~ 90%), and three-dimensional reticulated structure. As ceramic foam has excellent properties such like: high temperature resistance, strong chemical corrosion resistance, and large surface area as a result of high porosity, it is widely used in molten metal filtration to remove undesirable nonmetallic inclusions in the melt.

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 type of contaminant to be removed. Methods include spraying, brushing, backwashing, oven firing, dilute acid cleaning, solvent cleaning, steam cleaning and ultrasonic cleaning.

Applications
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.
