Honeycomb ceramics has high surfarce area, low air flow resistance. Catalyst carrier it can clean waste gas. Heat transfer agent: It can save 12% of energy in heat exchange. Refractory stove: Low mass/volume, fast heat conduction. Gas burn distributing plate: complete burn, energy saving is 10%.High surface area, large heat capacity, low thermal expansion, resistant to corrosion and high temperature, ceramic honeycomb monoliths have been well used in chemical, metallurgical, gas and environmental protection industries.
