sodium stannate is an inorganic substance with the molecular formula Na2[Sn(OH)6] and a molecular weight of 266.73. Insoluble in alcohol and acetone. When heated to 140℃, the crystal water is lost and anhydrous substance is formed. Absorbing carbon dioxide in the air to form sodium carbonate and tin hydroxide.
Mainly used in electroplating industry basic tin plating and copper plating, as well as tin alloy, zinc tin alloy, aluminum alloy and other alloys electroplating and electroless plating. Used in textile industry as fire retardant, weight gain agent. Used as a mordant in printing and dyeing industry. Also used in glass, ceramics and other industries.
Sodium stannate is widely used as oxidant and reducing agent in electroplating industry.
- It is also used in the preparation of special glass, ceramics and magnetic materials.
- Sodium stannate can be used as a preservative for treating wood.
- It is also widely used in other chemical fields.
