Mineralogy and Thermodynamics in Refractories

Mineralogical approaches including the work with phase diagrams can be very useful tools for the assessment of hot temperature properties and reactions occurring during wear of refractories. It does not require sophisticated computer programs to work with the diagram but only a ruler and a calculator. The paper describes the benefit of phase diagram work in the assessment of high alumina refractories by selected examples from high alumina castables for steel applications. The investigation of wear mechanism from Andalusite based castable as tundish permanent lining is another example provided.
