The Influence of Shaping Technique and Heat Treatment Conditions on the Microstructure and Thermoelectric Properties of TiO2 Ceramic

Abstract

It is well known that shaping technique can considerably affect various properties of ceramic materials. In the field of thermoelectrics, microstructure is one of the factors that has a great influence on materials thermoelectric properties. Although nowadays various advanced shaping techniques such as spark plasma sintering and hot presing have been widely used for preparation of thermoelectric materials, in the present work the effect of different convential shaping techniques: cold isostatic pressing and extrusion, as well as heat treatment conditions, on the microstructure and thermoelecric properties of TiO2 ceramic have been studied
