MarkeTech H-4 Honeycomb Ceramic (discontinued **)
Categories:	Ceramic; Oxide; Aluminum Oxide
Material Notes:	MarkeTech International special honeycomb ceramics have a uniform lattice structure, low expansion coefficient, good thermal shock resistance, higher specific surface area, low-pressure drop, and low density. They are available in cordierite or mullite ceramic. 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. MarkeTech International is no longer in business.
