The Texture and Heat Treatment of Hydrated Tin (IV) Oxides

1977
Various preparations of hydrated tin (IV) oxides are reported. These are classed as α- or β- stannic acids according to their stability in concentrated hydrochloric acid. Precipitation in the cold gives α- stannic acid, whilst preparations at high temper­ature result in β- stannic acid; the former being of smaller particles than those of the latter.

Synthesis of Tin Oxide Hydrate (SnO2 · xH2O) Gel and its Effects on the Hydrothermal Preparation of BaSnO3 Powders

Advanced Powder Technology, 2008
Perovskite-type BaSnO3 powders with a particle size of 30–60 nm have been prepared from tin oxide hydrate (SnO2 · xH2O) gel via the hydrothermal synthesis route. The reactivity of the synthesized SnO2 · xH2O was found to be dependent on the pH value of the mixture of tin chloride and the ammonia solution.
