Microstructural Characteristics of Refractory Composites

摘要

SEM, TEM and HREM have been used to study microstructural characteristics of oxide-nonoxide composites; commonly found microcracks led to improved thermal shock resistance. Appropriate amalgamation of refractory oxide and nonoxide may result in optimization of high-temperature properties. Ultimately, it also may lead to the development of a family of oxide and nonoxide composites for use in high-tech, high-performance refractory ceramics for high-temperature applications under specific severe service conditions.
