This study investigates the microwave synthesis of materials that typically require high temperatures (above 1200°C) through conventional heating to obtain the proper structures. For example, the garnet structured yttria alumina (YAG) require being held at 1600°C for several hours, and have to be put back through that process to achieve the proper crystal structure. Since the oxide constituents for YAG are transparent in a microwave, the aim of this study will be to adjust the intrinsic microwave absorbing nature of the precursor system with the addition of a carbon material. The work will focus on the effect of volume fraction, particle distribution, and percolation on the microwave coupling and heating event. The study will correlate these variables in order to produce a better understanding of a method to control the heating rate and reaction kinetics for the rapid formation of transparent refractory oxides, such as the YAG composition.
