What Are Porous Ceramics?
Porous ceramics are engineered materials featuring controlled void spaces within a ceramic matrix. By manipulating pore size and volume through processes like replica foaming or freeze casting, they deliver unique combinations of high surface area, low thermal conductivity, and mechanical robustness.
Key Properties & Material Variants
Al₂O₃ Porous Ceramics：High purity (>99.5%), excellent wear resistance, up to 1200 °C service temperature.
SiC Porous Ceramics：Superior corrosion resistance, thermal shock stability, pore diameter 0.5–50 μm.
ZrO₂ Porous Ceramics：Toughness and high-temperature strength, ideal for demanding catalytic supports.
Cordierite Porous Ceramics：Low thermal expansion, ideal for automotive and kiln furniture.

Applications of Porous Ceramics
FAQs About Porous Ceramics
Porous Alumina Ceramics feature high purity (>99.5% Al₂O₃), exceptional wear resistance, and thermal stability up to 1200 °C. These qualities make them ideal for liquid and gas filtration as well as catalyst support structures.
Porous Silicon Carbide Ceramics offer superior corrosion resistance and thermal-shock stability, with pore diameters ranging from 0.5–50 µm. They are widely used in high-temperature gas filters, heat exchangers, and as catalyst support in chemical reactors.
Porous Zirconia Ceramics combine high fracture toughness and elevated temperature strength, making them perfect for demanding catalytic support roles and structural components in energy and chemical processing industries.
Select porosity based on your application: high-porosity (60–90%) Macro-porous Ceramics suit filtration, while Micro-porous or mid-porosity variants balance surface area and flow resistance for catalyst support
Open-Cell Ceramics have interconnected pores that provide high permeability and large specific surface area, making them ideal for liquid/gas filtration, acoustic damping, and catalytic support.
We offer dimensional tolerances as tight as ±0.1 mm. Actual tolerances depend on the material (e.g., Porous Cordierite Ceramics) and the chosen manufacturing process to meet precision engineering needs.
