Porous Ceramics

Porous ceramics are a class of highly reticulated ceramic material that covers a wide range of structures, such as foams, honeycombs, interconnected rods, fibers, or hollow spheres.

Porous ceramics are featured in their unique combination of valuable properties, which makes them useful in a variety of special and advanced engineering applications. These properties are:

  • low density
  • low thermal conductivity
  • low dielectric constant
  • high thermal shock resistance
  • high specific strength
  • high chemical resistance

Typical applications for porous ceramics products include:

  • Thermal and acoustic insulation
  • Separation/filtration
  • Impact absorption
  • Catalyst supports
  • Lightweight structures
  • Porous burners
  • Energy storage and accumulation
  • Biomedical devices
  • Gas sensors
  • Sonar transducers
Porous ceramic products cover wide range of advanced ceramic materials, which can be oxides ceramics: alumina, zirconia, or non-oxides ceramics:carbides, borides, nitrides, silicides.

The properties of porous ceramic product depend on three main factors: the properties of the ceramic material of which the product is made; the topology (connectivity) and shape of the pores; and the relative density of the product.
