Abstract

Microwave heating(MH) has emerged in recent years as a new method for sintering a variety of materials against conventional sintering (CH) procedure. However,the phenomenon of microwave-materials interaction is still under debate. In this work,the effect of microwave heating on YIG phase formation was investigated at 1000ºC under the electromagnetic field(2.4GHz). The phase stability fired samples were qualitative and quantitative analyzed using X-ray diffraction(XRD)techniques. The obtained data were compared with CH to track the phase evolution. XRD revealed MHhas produced, YIG with 94% faster than CS. The calculated activation energy at this temperature via diffusion control model shows that MH(39.20kJ/mol)can effectively promote the phase growth rather than CH(90.96 kJ/mol).
