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. 548.5 tin dioxide gas-transport synthesis processing conditions nanocrystals morphology wire-like nanocrystals https://physmath.spbstu.ru/article/2010.6.2/
