| Abstract: | This paper reports the formation of alpha-Si3N4 whiskers through nitruration, at 1400 degrees C, of ash rice hulls, which constitutes a good source of amorphous silica and carbon, both in intimate contact. The structural and morphological evolution of silicon nitride during the conversion process was examined by X-ray diffraction and Scanning Electron Microscopy. |
