The automobile uses honeycomb ceramics as carrier. Owing to large specific surface area of the carrier, being able to be coated with the active catalytic components of precious metal enough, honeycomb ceramics are suitable for fabricating emission catalytic converter in diesel or gasoline vehicle to get through emission such as CO, NOx and hydrocarbon etc. purified.
Apply to NOx-removing systems for purifying the flue gas of the boiler firing coal at power plant, to harmful smog cleaning systems in combusting mass rubbish abroad. By the same token, honeycomb ceramics as carrier are generally utilized in chemical and mining industry for purifying noxious gas.
The heat-storing burners in metallurgical industry are recommended strongly fitted with honeycomb ceramics as heat-storing body, by the advantages of large specific surface area, small heat resistance, good thermal conductivity, excellent thermal shock resistance, realize quickly exchanging heat, reducing energy in the strict sense. In addition, honeycomb ceramics have significant use in filtering molten metal of special steel.
In the fields of mass transfer and separation in chemical and petroleum industry, the ceramic honeycomb structured packing is more efficient than the corrugated packing in improving uniform distribution of liquid, improving separation efficiency, solving amplifying effect, reducing resistance of packing stages and improving production efficiency etc.
Those like fuel gas stove adopt thinner honeycomb ceramics spacer covering on the fire mouth so that heat can be evenly distributed further to improve the effect saving energy.

3.Honeycomb Monolith medium material
High temperature air conflagration (HTAC) of thermal storage style is a new conflagration technology that has duplex efficacy of great power saving and environmental protection. Honeycomb monolith is the key components of the thermal storage style furnance, it is extensively used in many kinds of heater, sirocco furnace, heat treatment furnace, craking column, roaster, melting furnace, balance heating stove and etc. This technology can save more than 40-70% of power, increase more than 15% of production capability, depress 40% wastage of billet oxidization, reduce the Nox discharging to less than 100ppm, control the temperature of discharging smoke less than
