Design FeaturesPorous precision alumina ceramic filter cartridges, also known as ceramic honeycomb plungers, are made of high-performance alumina (Al2O3) ceramic and 

possess the following significant characteristics:

High Mechanical Strength and Wear Resistance

Alumina has a Vickers hardness of 15.7 GPa and a flexural strength of up to 330 MPa, ensuring durability and stability under high loads.

Excellent Heat Resistance and Chemical Stability

With a maximum operating temperature of 1650°C and good chemical inertness, it is suitable for use in high-temperature and corrosive environments.

High-Efficiency Filtration Performance

The porous structure design increases the surface area of the filter media, improving filtration efficiency while reducing pressure loss and optimizing 

hydrodynamic performance.

Excellent Thermal and Electrical Insulation

With a thermal conductivity of 27.5 W/(m.K) and a breakdown strength higher than 10 KV/mm, it is suitable for applications requiring insulation.
