Article Preview

This work suggested the growth of SiC and SiO2 nanostructures from heating of rice husk ash and carbon-metal assisted. The rice husk was boiled in 1 M hydrochloric acid solution with temperature of around 90 °C for 1 hour, and then washed in distilled water and dried under the sun. The dried acid-treated rice husk was burned in the furnace with normal air for 1 hour, then high purity SiO2 was produced. The high silica ash mixed with Cu or SnO2 powder and coconut shell charcoal were grounded for mixtures powder. The mixtures powder and Si substrates were placed on the alumina boat and put in the middle of furnace. The furnace was heated at high temperature under atmosphere of argon gas. The heated products and Si substrates were studied by X-rays diffraction and scanning electron microscope. The SiC and SiO2 nanostructures were observed.
