Silicon carbide with aluminium oxide was used to remove the sulphur hexafluoride () gas using microwave irradiation. The destruction and removal efficiencies (DREs) of were studies as a function of various decomposition temperatures and microwave powers. The decomposition of gas was analyzed using GC-TCD. XRD (X-ray powder diffraction) and XRF (X-ray Fluorescence Spectrometer) were used to characterize the properties of aluminum oxide. DREs of were increased as the microwave powers were increased. Additive aluminium oxide on SiC increased the removal efficiencies and decreased the decomposition temperature. The XRD results show that the was transformed to during decomposition by microwave irradiation. It was found that the best material to control was SiC with 30 wt% in consideration of microwave energy consumption and decomposition rate.
