摘要
The reactions between metastannic acid, powdered or granulated tin and 50-95 wt% H2SO4 are studied at and above room temperature, and with or without passing oxygen through the reaction mixtures. At least six different solid products, in addition to minor amounts of sulfur as a by-product, are obtained depending on H2SO4 concentration, reaction temperature, reaction atmosphere and tin form. TG and DTA curves are interpreted, unit-cell dimensions are derived from PXD data, and formulae based on chemical and TG analyses are given for the synthesized products.
