Product Description

What is Sodium Stannate?

Sodium Stannate Trihydrate is the sodium salt of stannic acid, an inorganic tin(IV) compound crystallized with three water molecules. Its high water solubility and tin(IV) content make it a standard industrial source of tin for alkaline plating-bath chemistry, and increasingly a precursor for engineered tin-oxide-based nanomaterials in materials-science research.

Uses of Sodium Stannate

Sodium stannate’s largest industrial use is as the tin source in alkaline electroplating baths, used to deposit tin coatings for corrosion protection and solderability in metal-finishing manufacturing. In materials-science research, it serves as a precursor for synthesizing lanthanum stannate and neodymium stannate nanoparticles, which have been used to modify glassy carbon electrodes and to develop selective analytical detection methods for compounds like dimetridazole in biological samples.

FAQs: Sodium Stannate

Mainly as the tin source in alkaline electroplating bath manufacturing, and as a precursor for tin-oxide-based nanoparticle synthesis in materials-science research.

Yes — it's classified Danger, causing severe skin burns and eye damage (H314) and toxic to aquatic life with long-lasting effects (H411); full PPE is recommended and it should not be released to waterways.

Both are tin(IV) sources, but sodium stannate is an alkaline, water-soluble salt commonly used in plating baths, while tin(IV) chloride is a different, more reactive tin(IV) precursor used in other synthesis contexts.

Yes, for every lot (SKU S3334).
