High strength 'engineering' ceramics have emerged as an important new class of structural materials within the latter half of the twentieth century. The silicon nitrides and their derivative 'Sialons', both of which are based largely on early research in the UK, have been particularly prominent in the field of engineering ceramics but have not fulfilled the early predictions for extensive ceramic substitution of metallic components. Reasons underlying the limited market penetration are based either on unacceptable component costs or on mechanical or thermal performance which has not achieved the levels based on optimistic extrapolation of early properties. Toughness is the most elusive goal which has promoted the evolution of ceramic matrix composites, based largely on spun-precursor fibres of SiC, with a recent drive to produce oxide/oxide systems with high temperature stability. The ability to relate 'model' structure and properties has enabled incremental advances in performance of real ceramics which are inevitably constrained by the requirements of convenient processing and fabrication. Examples are given of novel processing routes and microstructures within both monolithic and composite ceramics and their varied potential applications from ultra-hard tribological solids to high temperature components for engines of the twenty-first century.
