Ceramic Foam Filter

Ceramic Foam Filter

Ceramic Foam Filters are porous ceramic filters manufactured by impregnating a sponge carrier with ceramic slurry, followed by high-temperature calcination. They are primarily used in the foundry industry to filter molten metal during casting, removing non-metallic inclusions to improve casting quality and yield. Common materials include silicon carbide, alumina, and zirconia.

Our products feature high dimensional accuracy and excellent strength at both room and elevated temperatures, as well as outstanding thermal shock resistance and chemical stability. With a porosity of up to 80%, they effectively purify molten metal, enhancing the performance and quality of castings.

Ceramic Foam Filter

Alumina ceramic foam filter

Alumina ceramic foam filters have good chemical stability and high cost-effectiveness, and are commonly used in the purification process of aluminum alloy castings.

Ceramic Foam Filter

Silicon Carbide Ceramic Foam Filter

Silicon carbide (SiC) ceramic foam filters exhibit outstanding thermal shock resistance and high-temperature strength, making them particularly suitable for filtering molten cast iron, ductile iron, and other ferroalloy.

Ceramic Foam Filter

Zirconia ceramic foam filter

Zirconia ceramic foam filters possess excellent corrosion resistance and extremely high heat resistance, and are specifically designed for the purification of stainless steels and other high-temperature alloys.
