Insulating Fired Brick with 65% Al2O3 min High Alumina

Insulating Fired Brick with 65% Al2O3 min High Alumina 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. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

This series of High Alumina Insulating Fire Brick are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature.
