Porous ceramics filter and
Photocatalyst ceramics filter

Developing Strong, Lightweight, Highly Efficient Si/SiC Porous Ceramic Filters

Fusing Nippon Pillar Packing’s own technologies with those patented by the National Institute of Advanced Industrial Science and Technology (patent no. 3699992), we have succeeded in developing strong, lightweight, ultra-fine Si/SiC porous ceramic filters. Whether you need a filter that is flat, cylindrical, donut-shaped, or in any other form, we provide the filter to suit your design specifications.

Composition Bulk density Porosity Compressive strength Compression loss

Photocatalytic Ceramic Filters

By adding the benefits of our unique photocatalyst supporting technologies to porous ceramic filters, we have come up with superior photocatalytic ceramic filters. Harnessing the light transmission properties of porous ceramic filters, we have achieved a level of acetaldehyde, ammonia, and methylmercaptan degradability that is exponentially greater than conventional photocatalytic ceramic filters.
These new filters also offer the benefits of Si/SiC ceramic filters, and are available in any shape you need—cylindrical, donut-shaped, or any other.

Benefits of Porous and Photocatalytic Ceramic Filters

The high-strength, ultra-fine structure enables: ・Significant weight reduction (bulk density: 0.12g/cm³)
・Superior heat-resistance and shock-resistance of SiC materials
・Ultra-fine porous lattice, resulting in superior light transmission
・Ultra-fine porous lattice, resulting in minimal pressure loss
・Ultra-fine porous lattice, resulting in larger area per unit volume (specific surface area), increasing the amount of photocatalyst supported
・Our unique methods provide for sturdy support of catalyst
・Compatibility with multiple catalysts makes the material a versatile catalyst support
・Greater flexibility of shape and pore size.

Applications of Ceramic Filters

Making the porous ceramic filter out of Si/SiC enabled us to create a finer structure and resulted in greatly improved light, gas, and fluid transmission. Similarly, the more intricate filter structure means finer pores and a greater specific surface area. Consequently, these filters are ideal for use as catalyst support.
