SODIUM STANNATE
Sodium stannate trihydrate (sodium hexahydroxostannate(IV), Na2Sn(OH)6 / Na2SnO3·3H2O, CAS 12027-70-2) is a white powder made by dissolving tin or tin dioxide in sodium hydroxide. RXSOL's industrial grade carries about 42% tin (soluble Sn 40% min), free alkali 6% max as NaOH, insolubles 0.25% max, lead 0.05% max and stannite 0.1% max; density 4.68 g/cm³, melting point 140 °C. It is the electrolyte salt for alkaline tin plating, a stabiliser for hydrogen peroxide, a mordant in dyeing and printing, a fire-proofing agent for curtains and a raw material for other stannates and tin-oxide coatings.

Applications
Sodium Stannate is used as a stabiliser for Hydrogen Peroxide.
White to light tan crystals with a characteristic odour
Mordant in dyeing, ceramics, glass, source of tin for electroplating and immersion plating, tex- tile fireproofing, stabilizer for hydrogen peroxide, blueprint paper, laboratory reagent.
Sodium tin(IV) oxide is used as a mordant, fire retardant textiles.
Sodium stannate is used as a salt in alkaline tin plating electrolyte. It is used in surface coatings (paper). It is used in manufacturing other metallic stannates and tin oxide coatings.
The largest use for inorganic tin compounds is in electrolytes for plating tin and tin alloys. The more important plating chemicals are chlorides, sulfates, and fluoroborates in acidic electrolytes and stannates in alkaline solutions. Inorganic-tin compounds are divided into two series: stannous, or tin(II), compounds and stannic, or tin(IV), compounds.Chemically, tin exhibits valencies of 2 and 4. It resists attack by water but is dissolved by strong acids and alkalis. One of common compounds of tin(II) are stannous chloride (SnCl2) used in tin galvanizing, as a reducing agent in the manufacture of polymers and as a mordant in dyeing.; stannous oxide (SnO) employed in making tin salts for chemical reagents and for plating; and stannous fluoride (SnF2) is the additive in fluoride tooth-pastes. Inorganic tin chemicals are used as catalysts in a number of industrial processes. stannous octoate is the catalyst that produces the foaming action that turns the liquid plastic into a foamlike solid structure in the manufacture of polyurethane foam. Tin(IV) compounds of significance include stannic chloride (SnCl4) is widely used as a stabilizer for perfumes and as a starting material for other tin salts; and stannic oxide(SnO2) is a useful catalyst in certain industrial processes and a polishing powder for steel. Tin sulfide is used as a bronzing agent for wood colouring
