A study on microwave susceptor material for hybrid heating

Abstract

Abstract Efficient use of available resources at controlled and potential manner required a systematic approach for the technological advancement and creating product solutions. The proper choice of susceptor material for the desired heating rate is a prime concern for the effective utilization of microwave radiation and lower down the energy requirement. The present paper presents a comparative analysis of three different susceptor materials namely graphite boat, charcoal, and silicon carbide for the use in microwave hybrid heating (MHH). These susceptor materials are tested experimentally with 900W and 2.45GHz electromagnetic frequency to highlight the key role of a hybrid mode during microwave processing. The results claimed that the maximum temperature achieved in case of graphite boat is 350 0 C with 70 minutes of exposure. However, in the case of charcoal and silicon carbide, the maximum achieved temperature is 410 0 C and 255 0 C respectively at duration of 10 minutes.
