This book deals with synthesis of ZrB2 powder in the form of whiskers by carbothermal process and nanocrystalline particles by SHS process and study their sintering behaviour and compare the same with commercially available high purity ZrB2 powder. The cyclic oxidation of dense ZrB2 is investigated over the temperature range of 700-1200o C in static air condition. Attempts have also been made to study the production of the ZrB2-Cu composite and evaluate their behaviour as an electrical discharge machining (EDM) cutting tool. The synthesize powder shows better sinterability and oxidation...

This book emphasizes various aspects of EDM for the fabrication of advanced ceramics such as current status of EDM behaviour of advanced ceramics, production of ceramic powders by EDM technique, various modeling studies and material removal mechanisms of EDM. The new research directions of EDM on advanced ceramic materials like the application of ceramic matrix composites tools, use of different dielectric fluids and improvement of surface properties.
