Microwave synthesis and sintering characteristics of CaCu3Ti4O12

Bulletin of Materials Science, 2007
CaCu3Ti4O12 (CCTO) was synthesized and sintered by microwave processing at 2⋅45 GHz, 1⋅1 kW. The optimum calcination temperature using microwave heating was determined to be 950°C for 20 min to obtain cubic CCTO powders. The microwave processed powders were sintered to 94% density at 1000°C/60 min.

SINTERING OF MLCC’S BARIUM TITANATE WITH MICROWAVES

Proceedings 17th International Conference on Microwave and High Frequency Heating, 2019
A comparison of microwave and conventional, in an electric resistance furnace, sintered layers of dielectric base barium titanate (BaTiO3) of the kind employed for multilayer ceramic capacitors (MLCC) was performed. Two kinds of samples were used for each processing method; the layers alone without electrodes, and the green MLCC with the layers and ...
