• Vapor deposition products were formed in the cold zone(920-1120°C)during synthesis of SiC from carbonized rice hulls(CRHs)in the reaction zone(1500°C)of a vacuum tube furnace during carbothermal reduction. Crystals of gehlenite(Ca_2Al_2SiO_7)and β-SiC whiskers were identified by X-ray diffraction(XRD)and scanning transmission electron microscopy(STEM)to be the major deposits. A minor product, suessite(Fe_3Si), appeared to have eatalyzed the growth of gehlenite. The results of this study suggest the feasibility of preparing gehlenite materials by a vapor deposition process.
