MOLECULAR FORMULA: Na2SnO3·3H2O
Sodium stannate, formally sodium hexahydroxostannate(IV), is the inorganic compound with the formula Na2[Sn(OH)6].
This colourless salt forms upon dissolving metallic tin or tin(IV) oxide in sodium hydroxide, and is used as a stabiliser for hydrogen peroxide.
In older literature, stannates are sometimes represented as having the simple oxyanion SnO32−, in which case this compound is sometimes named as sodium stannate–3–water and represented as Na2SnO3·3H2O, a hydrate with three waters of crystallisation.
The anhydrous form of sodium stannate, Na2SnO3, is recognised as a distinct compound with its own CAS Registry Number, 12058-66-1 , and a distinct material safety data sheet.
Sodium Stannate is an inorganic metal oxide containing alkali metal sodium from group IA and post transition metal tin from group IVA in +4 oxidation state.
Sodium Stannate is generally immediately available in most volumes.
High purity, submicron and nanopowder forms may be considered.
Sodium stannate is widely used in the electroplating and tin alloy industries.
The traditional sodium stannate production processes suffer a variety of disadvantages including long flowsheet, high production cost and strict requirements for the equipment.
In this study, a novel process for preparing sodium stannate is developed by roasting tin dioxide and sodium carbonate in CO/CO2 mixed gas followed by leaching the intermediate products in a diluted sodium hydroxide solution.
Sodium stannate is a tin-based inorganic salt.
Sodium Stannate is commonly used as a stabilizer in hair dye products, helping to stabilize hydrogen peroxide in products.
