Synthesis of highpurity-SiC and-Si3 N4 from rice hulls.
Silicon carbide and silicon nitride were syntbesized from ashes obtained by heating rice hulls at 800C for 3 hours in argon. –SiC was produced from !he ashes by reheating tbem al 1400C fOl 8 hours in argon. whereas –S3N4. was obtained by heating tbe ashes al temperatures ranging from 1250C to 1400C...
