NaSnO3·3H2O SODIUM STANNATE TRIHYDRATE CAS 12027-70-2

SODIUM STANNATE TRIHYDRATE is a specific hydrated form of sodium stannate, valued for its stability and consistent performance in industrial applications. This compound serves as an essential source of soluble tin in alkaline environments. Its crystalline structure contains three water molecules, which contribute to its handling characteristics and solubility profile. Like the anhydrous form, it is fundamental to electroplating processes where it enables the deposition of smooth, adherent tin coatings on various substrates. It is also widely used in ceramic manufacturing and as a specialty chemical in other industrial sectors.

Application:

1.Electroplating Industry:

Used as the primary tin source in alkaline electroplating baths for depositing tin and tin-alloy coatings on metal surfaces, providing corrosion resistance and solderability.

2.Ceramic & Glass Manufacturing:

Acts as a mordant and opacifier in ceramic glazes, and as a raw material for producing pink pigments and specialty glasses.

3.Textile Treatment:

Serves as a fire-retardant and weighting agent for silk and synthetic fabrics.

4.Chemical Synthesis:

Functions as a precursor for other tin-based compounds and catalysts.

5.Surface Treatment:

Used in metal pretreatment processes to enhance surface properties before further finishing.

Safety profile:

SODIUM STANNATE TRIHYDRATE is alkaline and may cause skin and eye irritation. Inhalation of dust should be avoided. Use personal protective equipment (PPE) including gloves, safety goggles, and dust masks during handling. Although tin compounds generally exhibit low systemic toxicity, proper industrial hygiene practices are recommended. The material is not classified as flammable or explosively hazardous.

Storage requirements:

keep the product dry

relative humidity < 50%

protect product against influences of weather and contamination
