Abstract:
The products of the partial reduction of silicon from its dioxide are studied experimentally. Different ratios of silicon to oxygen ions are revealed on the surface of the initial phase and in the condensate of the reduction products having sublimated from this surface. The quenched condensate particles have a block structure with different atomic-packing densities and contain elemental silicon, silicon monoxide, and some undetected crystalline oxides, which are intermediate reduction products. A mechanism is proposed for the formation and sublimation of the products of incomplete silicon reduction. © 2008 Pleiades Publishing, Ltd.
