Probe the fundamentals in field-enhanced sintering process of high temperature ceramics via in situ TEM
Abstract
The proposal outlines the following main research tasks:(1) Synthesize selected high temperature ceramic (HTC) materials with tunable ionic conducting properties achieved through changingoxygen vacancy concentration (through both doping and processing parameter tuning) and investigate the ionic conductivity effects onthe overall sintering process using in situ heating and biasing TEM holder.(2) Process selected HTC materials with tunable grain boundary density to probe the effects of grain boundary density on the overallsintering mechanism using in situ tools.(3) Process composite systems of materials with mixed electrical and ionic conductivity, or superior and poor ionic conductivity system toachieve advanced grain boundary designs for HTC systems.
