摘要

Efficiency of microwave processing of partially or non-absorbing materials is strongly influenced by susceptor materials, which enable hybrid and rapid heating. This study investigates the mass-dependent heating behavior of morphologically distinct silicon carbide (SiC) and graphite susceptors under 2.45 GHz microwave radiation, alongside their environmental implications. Key parameters including heating capability, heating rate, mass loss, and carbon emissions were analyzed, and mass-dependent correlations were established. X-ray diffraction and thermogravimetric analysis were used to monitor phase alterations and degradation during microwave exposure. Results indicated an inverse relationship between susceptor mass and heating performance, while heating rates depended on morphology and chemical composition. Fine SiC powder (40 µm, 23 g) reached a maximum temperature of 2187 °C. Graphite exhibited unsteady mass loss and higher carbon emissions (9997 ppm CO, 6.38% CO2), whereas bulk SiC showed minimal emissions. Marginal β-to-α SiC conversion was detected, while graphite experienced minor surface degradation.
