Silicon carbide (SiC) was synthesized from Vietnamese rice husk and diatomite by electric arc discharge furnace with the arc current of 100, 150, and 200 A. The synthesized products were characterized by Raman spectroscopy, XRD, FE-SEM, and EDS. The result showed that α-SiC material with the purity of up to 85.12 % had been successfully synthesized from Vietnamese diatomite and rice husk charcoal. Also, there is remained amount of carbon and SiO2 which can be removed by burning and leaching processes.
