honeycomb ceramic
|
|
|
|
Products have
special honeycomb lattice structure, low expansion coefficient, good thermal
shock resistance, bigger specific surface area, small pressure drop, small
density. They're made of cordierite or mullite.
Cordierite honeycomb ceramics was mainly used in the
purification of waste gas of automobile, industrial organic, cooking stove
and melting metal. |
