Article Preview

In the frame of a wide research program devoted to the matter recovery from waste by means of thermal processes, particular efforts have been put into the study of biomasses and waste residue of peculiar composition, which could be used as precursors of ceramic materials. Rice shells are waste biomasses coming from the purification process of rice, which show a high carbon and silica content. The exploitation of these peculiarity promoted a series of experimental activities, aimed at the production of ceramic materials through high temperature carbothermal synthesis reactions. The synthesis products were characterized by X Ray Diffraction (XRD) and scanning electron microscopy (SEM) and the data confirmed the production of ceramic silicon nitride (Si3N4) at high yield and purity, under the adopted process parameters.
