Abstract

Ceramic nanocomposites are widely used as engineering materials owing to their excellent mechanical properties. In the last decade ceramic nanocomposites found new uses as a different kind of sensor. In this entry, examples of the preparation of electroconductive ceramic nanocomposites are shown together with their utilization as self-monitoring sensors for crack initiation and propagation. Four different methods for synthesis of nanocomposite ceramics are presented, and their effects on the structure of nanocomposites are compared. The self-diagnostic ability of graded and layered ceramic nanocomposites was not accompanied by any sizable deterioration of mechanical properties.
