Brief indroduction of porous ceramic is powered by Tangshan HanWei.

The porous ceramics is a kind of (inorganic non-metal material)powder sintered ceramic, compared with compacted ceramic, biggest difference is whether has blowhole & the volumn of the holes, the porous ceramics can be divided into foam ceramics, honeycomb ceramics,grains ceramics, and their features as follow:

1)      Small volumn density, lighter weight;

2)      Bigger ratio surface, excellent filtering work;

3)      Lower thermal conductivity, heat & noise insulation;

4)      Good chemical & pysical durability, fit on most corrosion environment, good machenical strength and high temperature resistance;

5)      Simple process, lower cost.

Due to above features, it mianly used as filters, so the porous ceramic is widely used on many many fields,  like melten metal filtering, high temp air cleaning, water treament,noise-reducer, Diesel Particulate Filter for auto, electric ceramic parts etc.

High temperature filter ceramics material can be :

Aluminum oxide, mullite,cordierite, Zirconium oxide, silicon carbide etc.

While the the porous ceramics sintering temperature is very high, 1300-1700 degress Centigrade, thus the kiln furniture parts must be very high-temp resistance & strength, Tangshan HanWei Trading is offering Silicon Carbide Ceramic kiln spares with most competitve price & high quality, our SiC ceramics is an ideal substitute of Sain-Gobain ceramics, for saving your production cost, please contact China Silicon Carbide (SiC) Ceramics factory / Supplier : visit our web WWW.HW-BIZ.COM for for info about Tangshan HanWei, we can design right plan for you.
