Stannous sulfate is the sulfate salt of stannous. Study has shown that it can be mixed with gypsum to make a retarder in grinding portal cement and blended hydraulic cement, which can improve the quality of the cement, mortar and concrete. It can also be used as the reducing agent during the determination of mercury, cobalt and nickel through atomic absorption spectrophotometry. It can also be used as an electrolyte additive to be supplemented to the battery. This could have a positive effect on restraining larger particles of irreversible sulfation in charge-discharge cycles of battery testing.
| [Description]
Stannous Sulfate is a white to slightly yellow, heavy crystalline powder. When dissolved in a 5% Sulfuric Acid Solution, a clear solution is obtained. Gradual hydrolysis occurs over a period of time with the formation of insoluble tin compounds.
Stannous Sulfate is commonly used in acid tin plating baths, liquor finishing and drawing of steel wire. It delivers a high current efficiency and smooth, fine grained deposits. A bright finish can be obtained by flow melting of through the use of certain additives.
