Preparation of SiC Powders by Utilizing Rice Husk Ash from Biomass Cogeneration Plant

Abstract:

A large amount of rice husk ash (RHA) is produced in the biomass cogeneration plant using rice husk as fuel. For utilization of this kind of industrial waste, SiC powders were synthesized with RHA and carbon black calcined at the temperature from 1500 to 1650 °C in argon. The phase composition and microstructure of samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effects of temperature and SiO₂/C ratio on the synthesis of SiC powders were investigated. The results show that the formation of SiC increases with SiO₂/C ratio increasing as a whole, and SiC whisker appears at the temperature up to 1650 °C. The optimal temperature and SiO₂/C ratio are 1550 °C and 5:8 respectively.
