Abstract
New ceramic composites have been synthesized upon combined use of mechanochemical treatment (MCT) of SiO 2 , its thermal carbonization (followed by baking), and SHS in a mixture of thus activated (carbonized) SiO 2 with Al powder. MCT and thermal carbonization were found to result in formation of fiber-like carbon structures on the surface of silica particles. The rigid carbon frameworks formed on the surface of silicon dioxide were found to improve the physicochemical properties of resultant carbon-containing refractory materials.
