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.
