STANNOUS SULFATE

EC / List no.: 231-302-2
CAS no.: 7488-55-3

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.
Stannous Sulfate 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.

Stannous Sulfate is a white solid that can absorb enough moisture from the air to become fully dissolved, forming an aqueous solution; this property is known as deliquescence.
Stannous Sulfate can be prepared by a displacement reaction between metallic tin and copper(II) sulfate:

stannous sulfate solution is well know for its chemical characteristics with a content of 225 grams per liter.
This mass concentration of Sn SO4 optimizes your process and productivity.

Uses: tin sulfate solution is mainly used for coloring aluminum profiles by an anodizing process in the building industry.
Stannous sulfate is also used in electroplating, for electrolytic tin plating (tinning).
Finally, Stannous Sulfate is used as a raw material for the production of tin chemicals.

Many stannate tin platers have converted to acid sulfate.
Room temperature operation, expedited reaction, greater anode efficiency, and a bright finish or matte finish options may be listed among the advantages.

The inception of acid sulfate electroplating was in the electronics industry.
Currently, however, any plater untroubled by the hydrogen embrittlement will utilize an acid sulfate process.
Because the anode provides all the necessary tin, only a minimal quantity of Stannous Sulfate is requisite in order to maintain the plating bath.
Thus, there is a profusion of companies of modest capacity with a requirement for electroplating Stannous Sulfate.

The recently expanded market for Stannous Sulfate has developed during the past 15 years.
Color anodizing aluminum for architectural or automotive applications has become a major outlet for Stannous Sulfate.
Two binary procedures are employed. In both of these two step processes either all or one half of the tin emanates from the sulfate.
One process utilizes inert electrodes, and the other uses tin electrodes.
Therefore, the sulfate consumption varies.
Almost one half of the Stannous Sulfate consumed in the United States is for color anodizing.

Stannous Sulfate is a moderately water and acid soluble Tin source for uses compatible with sulfates.
Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal.
Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble.
Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions.
Metallic ions can also be dispersed utilizing suspended or coated nanoparticles and deposited utilizing sputtering targets and evaporation materials for uses such as solar cells and fuel cells.
Stannous Sulfate is generally immediately available in most volumes.
High purity, submicron and nanopowder forms may be considered.

Stannous Sulfate can be used in the electrosynthesis of Cu2ZnSnS4 (CZTS) thin films for solar cell application.
Stannous Sulfate can be used to synthesize ternary Cu-Sn-S chalcogenides such as Cu2SnS3, Cu5Sn2S7 and Cu3SnS4 by successive ionic layer adsorption and reaction (SILAR) method.
