Abstract
Abstract An additive is mixed with material to be subjected to microwave heating to increase the coupling or effectiveness of the heating. The additive has a substantially greater coupling factor than that of the material to which it is added. The material is selected from CO3O4, CrN, FeO4, MnO2, NiO, Ni2O3, or a composition resulting from the mixture of Al2O3 and CaO with any water driven off, or a mixt. of these. Both the additive and the subject material should be granular and in the case of the Al2O3, CaO mixture, Al2O3 forms 90% wt. the CaO having an 8-15% water.
