Notes:
Abstract SnO2 sols were prepared in the following way: (1) precipitation of metastannic acid with aqueous ammonia from aqueous solutions of SnCl4, (2) washing the precipitates with NH4NO3 solution and water, (3) peptization of precipitates in water, sometimes with an addition of HNO3, at elevated temperature using mechanical stirring. In those sols, sometimes diluted with water or ethanol, substrates (glass or silica derived wafers) were dipped and withdrawn at various rates. Gel coatings were converted into crystalline SnO2 by thermal treatment at 600°C. Coatings with thickness between 300–2000 Å were prepared.
