The conversion efficiency of electrical to microwave power by magnetrons operating at 896/915 MHz is significantly greater than that of magnetrons operating at 2.45 GHz. The increased efficiency at this frequency improves the prospects of microwave firing being adopted as a commercially viable process but the change in frequency alters the microwave-material interactions that take place. This paper discusses the influence and implications of using 896/915 MHz for firing ceramics and compares dielectric property data at both frequencies. The results suggests that using the lower frequency will result in more efficient heating.
