Zirconia Foam Description
Zirconia Foam is a high-performance porous ceramic material engineered for extreme-temperature filtration and insulation applications. Manufactured using high-purity zirconia, it withstands continuous use in environments reaching up to 1700°C, making it ideal for filtering molten stainless steel, carbon steel, and large iron castings. Its 3D interconnected pore structure enables excellent removal of non-metallic inclusions and refines molten metal flow by converting turbulent streams into uniform laminar flow. This not only enhances casting surface quality but also minimizes internal defects and lowers rejection rates. Thanks to its high thermal shock resistance, mechanical strength, and chemical inertness, zirconia foam is the preferred choice for advanced foundries, metallurgical processing, and other high-temperature applications requiring precision and reliability.

Zirconia Foam Applications
- High-Temperature Filtration: Zirconia foam is used in molten metal filtration, especially for steel and alloys, due to its excellent thermal stability and corrosion resistance.
- Catalyst Support: Its high surface area and chemical inertness make it an effective support material for catalysts in chemical reactions and fuel cells.
- Thermal Insulation: Zirconia foam serves as an insulating material in furnaces and kilns, capable of withstanding extreme heat without degradation.
- Biomedical Applications: Biocompatible and stable, zirconia foam is applied in bone scaffolding and dental implants in regenerative medicine.
- Gas Diffusion Layers: In solid oxide fuel cells (SOFCs), zirconia foam is used to distribute gases evenly and enhance electrochemical performance.
