Abstract

Microwave heating is a green technology that provides many advantages over conventional heating. In this paper, we analyse some composite ceramic materials, formed by barium carbonate and hematite powders. There were used three mixtures with micron, submicron and nanometric particles size. All the mixtures were sintered in microwave hybrid field using a new differential thermal analysis technique. For this type of materials it was necessary to optimize the heating process and has been found that the microwave sintering time is very short, in the order of minutes, compared to resistive heating, which is a great advantage in terms of process productivity. Using differential thermal analysis in microwave hybrid field, the sintering temperatures of the magnetic ceramic materials could be identified. The sintering temperature of the sample from nanometric powder mixture decreased by about 20% compared to the sintering temperature of the sample from micron powder mixture. The use of the nanometric mixtures in experiments is advantageous as it ensures high productivity, low sintering temperatures and very good magnetic parameters.
