Zirconia Foam - Ceramic Filter for Foundry
Zirconia foam, the ZrO2 ceramic foam filter, is a type of porous material with interconnected pores, known for its high-temperature resistance and excellent filtration properties. It is commonly used in metallurgical industries for purifying molten metals and alloys, such as cast iron, steel, copper, and other alloys. The porous ceramic filter is characterized by the following:
- High Porosity
- Large Surface Area
- Robust Mechanical Strength
- Thermal Shock Resistance
- Chemical Corrosion Resistance
- Filtration and Adsorption Properties

What is Zirconia Foam?
SEFU zirconia foam filter is a highly refractory casting material and can withstand temperatures of up to 1700°C, making it an ideal choice for filtering high-temperature metal alloys, including stainless steel, carbon steel, and large cast iron.
The molten metal filter is widely used in the manufacturing of automotive parts, aerospace components, machinery parts, and other high-temperature precise casting applications.
Features of Zirconia Foam Ceramic Filters
- High Porosity: It allows for the efficient filtration of molten metal and removes impurities, resulting in high-quality metal products.
- Large Surface Area: It provides a vast amount of area for metal to flow through, ensuring that metal is distributed evenly and reducing the risk of turbulence.
- Thermal Shock Resistance: It can withstand extreme thermal shocks, which occur during filtering, reducing breakage and ensuring durability.
- Chemical Resistance: Zirconia foam filters can withstand contact with chemicals and molten metal.
- Excellent Mechanical Strength: Zirconia filters are durable and have excellent mechanical strength.
- Filtration and Adsorption Properties: It removes impurities and enhances the quality of metal products.
