1. Description
Direct bonded magnesia-chrome brick is made of high purity or sub-high purity sintered or fused magnesia and chrome concentrate as raw materials. Direct bonding is a kind of bonding produced by direct contact between solid grains. The brick is made of high purity sintered magnesia and chromium concentrate with SiO2<2% as raw materials through high temperature sintering. The direct bonding degree of the product increases with the decrease of SiO2 content and the increase of firing temperature.
