Ceramic foam filter is a porous ceramic material made from high-purity raw materials such as zirconia, silicon carbide, and alumina. The most common types include zirconia ceramic foam filter for steel casting and sic ceramic foam filter for non-ferrous metals.

The foam ceramic blocks feature high porosity (up to 90%), large surface area, and uniform pore distribution, allowing molten metal to flow smoothly while trapping impurities.

As experienced ceramic foam filter suppliers, we provide customized pore size (PPI), dimensions, and material compositions to meet different industrial requirements.

Types of Ceramic Foam Filter

Zirconia Ceramic Foam Filter

Zirconia ceramic foam filter is specially designed for steel and alloy casting. It can withstand extremely high temperatures up to 1700℃ and resist corrosion from molten steel.

The zirconia ceramic foam filter effectively removes inclusions, reduces gas defects, and improves metal purity, making it ideal for high-grade steel casting applications.

SiC Ceramic Foam Filter

SiC ceramic foam filter is mainly used for cast iron, copper, and aluminum filtration. It offers excellent thermal shock resistance, high strength, and stable chemical properties.

The sic ceramic foam filter ensures smooth metal flow and reduces turbulence, improving casting quality and reducing scrap rate.

Foam Ceramic Blocks

Foam ceramic blocks are general porous ceramic materials used not only in filtration but also in catalyst carriers, heat exchange media, and environmental protection systems.

Thanks to their high surface area and stable structure, foam ceramic blocks are widely used in both industrial filtration and chemical processing.
