ON THE MICROWAVE SINTERING OF BATIO3 BASE D FUNCTIONAL CERAMICS

On the base of cooperative thermic and electrodynamic effects (''micro wave effect'') the application of microwave energy opens new and effec tive technological possibilities for materials science as well as in t he field of preparative chemistry In the following the efficiency of m icrowave sintering with respect to the ''tailoring'' of the microstruc ture and functional (electrical) properties will be described. First o f all the main interest was directed to comparative studies of microwa ve and conventional sintered bodies with respect to their shrinkage be haviour and microstructure development. First results are presented in connection with secondary phase promoted microwave sintering using Cu - and SiC-doped BaTiO3 ceramics.
