| Abstract: | An improved process for the preparation of SiC from rice husk, which comprises cleaning and drying of raw rice husk by conventional methods, subjecting the cleaned and dried rice husk to thermal plasma at a temperature in the range of 1200 to 2500oC for a period of 15 to 45minutes in an inert atmosphere, powdering the resultant product by conventional methods, removing excess free in the powder so obtained by heating the powder at a temperature in the range of 700 to 900oC for a period of 1 to 3 hours in an oxidizing atmosphere, removing unreacted silica by hydro-fluoric (HF) treatment to obtain silicon carbide (SiC). | ||
| Licensing Option: | Laboratory scale know-how is available. | ||
