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...
