A morphology of tin oxide nanocrystals obtained by gas-transport synthesis

An analysis of processing conditions of gas-transport synthesis of tin oxide wire-like nanocrystals is presented. The dependence of SnO[2] crystals morphology on the composition of source charge, and the gas-carrier, on oversaturation degree for vapour-phase material in the growth area of the crystals was experimentally determined. As a result of the gas-transport synthesis bulk microcrystals, fractal-like nanocrystals were obtained as well as wire-like crystals with a diameter of filaments from 1000 to 50 nm.
