As a kind of composite refractory material, magnesia-carbon brick
makes good use of the strong slag erosion resistance of magnesia
and the high thermal conductivity and low expansion of carbon, and
compensates the biggest shortcoming of the poor spalling resistance
of magnesia.
Its main characteristics are: good high temperature resistance,
slag resistance, good thermal shock resistance, high temperature
creep is low.
