Unburned high alumina brick refers to the high alumina brick that is not fired at high temperature. By adding small particle wax stone raw material, the compressive strength is increased and has the properties of micro expansion and residual expansion. An appropriate amount of SiO2 and alkaline substances form a dense protective layer on the hot surface to prevent the further infiltration of alkali metals, and improve the anti peeling, structural peeling and alkali erosion properties of the brick.
