As a result of continuous development in the last five years, HP Technical Ceramics can now offer porous ceramics with serialized pore size distributions.
Although the main compositions of the porous ceramics are alumina and fused silica, we can also manufacture other materials such as silicon carbide etc.
In
most cases, the porosity of these ceramics can be varied from 20% to 60% by volume.
The porous structures are always interconnected. Liquid and gas can
flow through them with low pressure drop.
The pore size, depending on the manufacture technique used, can be controlled to as small as
10 nanometers with a narrow pore size distribution. However, the
shape of the porous ceramic may be limited when pore sizes approaches the
lower limit.
The porous ceramics are produced in any shapes according to customer's design. Typical shapes already manufactured include rods, tubes,
and thin plates.
A sol-gel technique is used to produce porous ceramic media in forms of
spheres, flakes and irregularly shaped particles. Such ceramics have enormous surface areas up to 500
m2 per gram and are applied as high
performance catalyst carriers or supports for various chemical reactions.
The excellent inertness of ceramics offers a easy way of
sterilization as compared with plastics and other materials.
