Preparation and characterization of valuable materials from Rice Husk Ash

Abstract

Rice husk is a by-product of rice obtained from rice processing industries having a wide range of applications in the synthesis of certain important functional materials such as silica, activated carbon, carbon nanotubes, silicon, etc. Rice husk is rich in silica; the silica obtained from rice husk (RH) is in the amorphous phase with greater purity as compared to that of silica acquired from rice husk ash (RHA) which is in the crystalline phase. Current research deals with the synthesis of rice husk ash from rice husk and also the synthesis of Activated carbon, Silica, and Furfural from rice husk ash and the characterization of ash and all the synthesized materials. Dried rice husk was procured from Rajura Mill of Rice, Rajura, Chandrapur, and from this rice husk prepared rice husk ash, which was evaluated for Chemical analysis, Fourier transforms infra-red spectroscopy, X-ray diffraction, and Scanning Electron Microscopy and then used for the synthesis of activated carbon, silica, and furfural. The synthesized materials, then evaluated for Fourier transforms infra-red spectroscopy, X-ray diffraction, and Scanning Electron Microscopy. The results of obtained materials proved that they have desired properties that are having multiple of applications, so it will be beneficial to produce this kind of materials from rice husk ash.
