A detailed review of ceramic composites was considered, taking into account the details of the constituents, that is, the matrix phase, the reinforcing phase, and the interfacial domain. Advanced ceramics exhibit a combination of properties: high strength at elevated temperature, high hardness, good corrosion and erosion behaviour, high elastic modulus, low density and generally low coefficients of friction, that make them potential candidates for many structural applications. Ceramic matrix composites (CMCs) are an attractive alternative because they maintain the refractory properties of monolithic ceramics and do not exhibit a catastrophic failure mode. This review provides a comprehensive overview of the current state of understanding of ATZs. under “cold” and “wet” conditions. 1. Abstract. In addition to size, shape, and distribution and etchability of the phases, light reflectivity is a criterion for distinguishing and identifying the phases in a ceramic. Abstract.
