Crystallization of Rice Husk Produced Silica and Silicon Carbide

Abstract:

Vietnam is one of the largest rice producers in Southeast Asia, generating substantial quantities of rice husk as a by-product of rice milling. Currently, rice husk is predominantly disposed of as agricultural waste. This study investigates the utilization of rice husk to synthesize silicon carbide (SiC) and crystal silica (SiO₂). The device for the experiment was built by the authors with simple accessories. SiC and crystal SiO₂ from rice husk were synthesized successfully at low temperatures compared to a chemical reaction of silica reduced by carbon. The research outlines the production conditions for achieving a little SiC from recycled rice husk and explores potential development pathways for applying this technology in structural and material manufacturing industries. The characterization of the synthesized SiC was measured using X-ray diffraction (XRD) and scanning electron microscopy (SEM).
