Cordierite Plate Brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life.
Feature：
5.These can be machined to special shapes, incurring fewer sections and joints
