Abstract
This work deals with the evaluation of two microwave cavity geometric shapes used experimentally to obtain reaction rates of iron ore pellets in a carbothermic reduction process. Parallepipedic and hexahedral cavities were used. Computer simulation showed more uniform spatial distribution of the electromagnetic field in the hexahedral geometry which also had better energy efficiency. A complete 2 3 factorial experiment was planned to quantify influences of important variables. Experimental real data confirmed the hexahedral geometry superiority suggested by the electromagnetic computer simulations.
