Development and characterization of conventional and microwave Sintered niobia co doped yttria Stabilized cubic zirconia

Abstract

Ceramic technology has been identified as the field of high temperature newlinetechnology because high temperatures are usually involved either in newlinemanufacture or in applications Over the past few years ceramic materials newlinehave found increasing use on both structural and functional components newlineowing to their excellent properties The key to the development of reliable newlinestructural ceramics is to improve the reliability and toughness while retaining newlineother desirable properties such as light weight strength and hardness newlineThis can be achieved by creating flaw tolerant microstructures newlineThe micro structural control transformation toughening and newlineceramic matrix composite technology are often used to improve newlinethe fracture toughness and reliability of ceramics newlineZirconia undergoes a displacive transformation on cooling at newlinetemperatures between 1200 and 1000 C newline newline
