Honeycomb Ceramic is porosity ceramic with parallel holes shaped as triangle, square or hexagon. The honeycomb units are separated by thin wall and they are used in the industry extensively. Currently the materials for products are mainly, Cordierite, Mullite and Corundum. This product is mainly used in metallurgy, tower packing in chemical industry, construction, heat-regenerative and high-temperature air purification, industrial waste gas treatment.
