Introduction:
Potassium Stannate is a white, crystalline inorganic compound with the chemical formula K₂SnO₃ or K₂SnO₃·3H₂O (in hydrated form). It serves as an important source of tin in various industrial and electroplating processes. Known for its excellent solubility in water and strong alkaline nature, Potassium Stannate is widely used in metal finishing, textile treatment, and chemical synthesis.
 
Applications:
Electroplating Industry: Used as a source of tin ions in alkaline tin plating baths to produce smooth, corrosion-resistant coatings.
Metal Surface Treatment: Plays a role in pre-tinning and metal cleaning operations.
Catalyst Preparation: Acts as a precursor in the preparation of tin-based catalysts for industrial processes.
Textile Industry: Used as a mordant and in fire-retardant fabric treatments.
Glass & Ceramic Manufacturing: Improves transparency and chemical durability of glass and ceramic glazes.
Chemical Industry: Serves as a reagent or intermediate in the production of other tin compounds.
 
Benefits:
Excellent solubility and dispersion in aqueous systems.
Provides consistent tin coating in electroplating.
Enhances corrosion resistance of metal surfaces.
Offers good thermal and chemical stability.
Environmentally more acceptable compared to acidic tin salts when handled properly.
