Research Topic
We
are investigating electroceramics for dielectric, piezoelectric and
thermoelectric applications. Pursuing NEW
PROCESS and NEW MATERIAL are key
strategies in our research. First, new process is based on sonochemical process,
which uses ultrasonic energy to activate the raw materials to be transformed
into a designed electroceramic powder through calcination process. We have
adapted sonochemically activated solid-state reaction for the synthesis of
well-known electroceramics, like BaTiO3. The sonochemical process
can enhance the solid-state reaction significantly without loss of dielectric
properties as compared to the conventional solid-state reaction and we have
reported detailed mechanism for the enhancement. We believe that this
sonochemically activated solid-state synthesis will be effective in developing
a time-saving, contamination-free, and cost-effective process in highly
competitive MLCC and various ceramic industries, through further process
optimization. Second, we are exploring new electroceramics for use in
dielectric, piezoelectric and thermoelectric applications. Perovskite oxides
are our basic materials. We have been working to modify the specific
compositions in the perovskite oxides to improve the properties for each
application and now we are focusing on stanate-based perovskite oxides.
