Production of silicon carbide powder from rice husk/Rice husk ash (RHA)

Advantages / Salient Technical Features Application/Uses
• Plasma processing is very fast and efficient. Raw • Iron and Steel Sector Abrasive Industries
material is waste. Purity obtained is at par with Automobile Industries (Brake pads, Wheels)
industry requirement Coating Industries: Sliding surfaces, rollers,
machine parts for chemical and petro- chem-
Problem being addressed ical industries,gate valves, pumps, mechani-
cal gears, seals etc.
• Waste like rice husk is creating huge land/soil pollution
in major rice producing states in India. Burning it in
open creates lot of pollution Scale of Development
• Bench Scale (Current TRL Level : 04)
Environmental Considerations (if any)
• Utilization of waste like rice husk/RHA will reduce Commercialization Status
soil/ land pollution thereby giving a positive impact • Not yet
on environment

Techno-economics
Major Raw Materials to be Utilized • NA
• Rice husk RHA
