REFRACTORIES & CERAMICS
 
Refractory materials must be chemically and physically stable at high temperatures. Depending on the operating environment, they need to be resistant to thermal shock, be chemically inert, and/or have specific ranges of thermal conductivity and of the coefficient of thermal expansion.  Natural Graphite is the key additive in many specialized refractories like magnesia-carbon bricks
