This paper reports obtaining of useful and highly value materials from wheat bran. For this purpose, wheat bran sample was burned for 30 s using Nd: YAG laser with output power 60 W. The product of synthesis process and non-burned wheat bran were characterized by x-ray diffractometer (XRD), energy dispersive x-ray (EDX) and Fourier transform infrared (FTIR) so as to investigate its crystal structure and chemical components. XRD results of the sample before burning process revealed amorphous silica and cubic phase of silicon carbide. The obtained results showed that burning process using Nd: YAG laser can convert the cubic structure of silicon carbide into hexagonal and rhombohedral structure and convert rhombohedral structure of carbon into hexagonal structure; also it revealed a monoclinic structure of silica after burning. FTIR showed a number of absorbance peaks assigned to silica and silicon carbide.
