Natria stanata uzatas kiel stabiligilo por hidrogena peroksido kaj kiel duonkonduktilo. Stanatoj troviĝas sub du formoj: metastanatoj prezentantaj la jonon SO3−2 kaj ortostanatoj aŭ SO4−4.

, Sodium stannate, formally sodium hexahydro … 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. Alkali metal stannate compounds are prepared by dissolving elemental tin in a suitable metal hydroxide, in the case of sodium stannate by the reaction: Sn + 2 NaOH + 4 H2O → Na2[Sn(OH)6] + 2 H2 A similar reaction occurs when tin dioxide is dissolved in base: SnO2 + 2 NaOH + 2 H2O → Na2[Sn(OH)6] The anhydrous form can also be prepared from tin dioxide by roasting with sodium carbonate in a mixed carbon monoxide / carbon dioxide environment: SnO2 + Na2CO3 → Na2SnO3 + CO2 The anion is a coordination complex that is octahedral in shape, similar to most stannates, such as the hexachlorostannate anion [SnCl6]2−. The Sn—O bond distances average 2.071 Å.. The Sn—O bond distances average 2.071 Å.
