Ceramic honeycomb description:

It is one kind of industrial porous ceramics, many passable parallel channels are ramified over its inside.

Each individual part made up of these honeycomb ceramics are constructed into the shape with square cells at two ends.

Ceramic honeycomb feature:

regenerator is the key and core component on high temperature air combustion technology. It has large specific area, specific heat, low coefficient of thermal expansion.

Ceramic honeycomb Application:

catalyst carrier for automobile and motorcycle waste gas purification
