Zhongci Alumina Ceramic Foam Filters for Foundry
Alumina ceramic foam filter is a kind of effective molten metal filter. It’s three-dimensional connected mesh structure and high porosity has many advantages,for example, large surface area of slags collection.large inner surface area of filtering,small flowresistance,good filtering efect,etc.

Alumina Ceramic Foam Filters for Foundry Feature
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.
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 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.
Alumina ceramic foam filter 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.
