Abstracts

Refractories, otherwise known as Controlled Microstructure Nanobonded Ceramic Composites1, have been used in extreme environments for centuries. The concept ofin situ protective behaviour emerged in the 20th century by which the refractory furnace lining reacted with the contents in a beneficial way to produce a protective interlayer2. Control of local equilibrium3 is crucial to extending refractories life. This lecture will examine, using examples from the authors own work, current development of structural ceramics for use in the extreme environments of future refractory, aerospace4 and nuclear5 applications. It will include consideration of high temperature, corrosive atmosphere and intense radiation flux (and sometimes all three).
