The main objectives of parts I and II of this paper were: basic criteria for the improvement of thermal shock resistance of engineering ceramics; data about the thermal stress resistance of high‐strength engineering ceramics (thermal shock and thermal cycling); and the influence of microstructure on thermal shock resistance to fracture initiation, including the influence of various microstructural variables on the mechanical and thermal properties which mainly control the thermal shock resistance to fracture initiation. In part III of this paper the possibility to improve the thermal shock resistance to fracture initiation by microstructural optimization is demonstrated. This includes a description of the different steps of the improving procedure. Moreover, the improvement of thermal stress resistance by developing advanced composite materials based on theoretical considerations of improving some important properties by microstructural design is outlined. Here the results of previous investigations and of recent developments are summarized.
