Honeycomb
HONEYCOMB CERAMICS
Marketech special honeycomb ceramics have a uniform lattice structure, low expansion coefficient, goodthermal shock resistance, higher specific surface area, low-pressure drop, and low density. They're made of either cordierite or mullite ceramic materials. Cordierite honeycomb ceramics are mainly used as catalyst support for the automobile and for purification waste gas of industrial organic processing, and as filters in melting metal.
