China Ceramic Honeycomb Heater Gas Refractory

Honeycomb ceramic-heat accumulation substance
Honeycomb ceramic are made of corundum-mullite, cordierite-mullite, cordierite, mullite, zirconia-mullite, carbo-corundum and so on with different hole shapes, such as square hole and hexagon hole, different wall thicknesses from 0.5mm to 5mm, and different figure specs, such as 100x150x100mm,100x100x100mm, 150x150x150mm, 150x150x300mm, and so on.
Ceramic Honeycomb as the media of heat storage and heat exchange, has been widely applied in the fields of metallurgy, petroleum & chemical industry, electric power, boiler and so on.
It has high surface area,small resistance and thermal expansion,strong chemical corroding resistance,excellent thermal shock resistance.
