  • Description
  • Low porosity clay brick is made of high quality coke gem clinker, sintered mullite, three stone as the main raw materials by sintering at high pressure and high temperature. It has the characteristics of low apparent porosity, strong permeability resistance, strong erosion resistance, high compressive strength, and good thermal shock stability at low temperature. Mainly used in the glass furnace regenerator in the lower part of the lattice body and wall parts.
