Without refractory materials most of the scientific and technological inventions and developments we know today would not have been possible. The existence of virtually everything we see around us, or use in everyday life, is in some way dependent on refractory materials. Refractories are therefore facilitating or enabling materials, and are essential to the successful operation of any industry in which high temperatures are used1,2,3. The word `refractory` is derived from the Latin word, `refractories`, which means stubborn 4. These materials resist high temperatures, have high-quality mechanical and thermomechanical properties, have high corrosion resistance, act as a heat buffer between the walls of the containing vessel and the hot charge, and conserve process heat1,4,5. Reliability and long service life are required from materials when put into operation. Refractory cost is therefore expressed in terms of tons of product produced, i.e. the cost of the refractory material is weighed against useful life and replacement cost.
