|Section2= |Section3= }} Sodium zincate refers to anionic zinc oxides or hydroxides, depending on conditions. In the applications of these materials, the exact formula is not necessarily important and it is likely that aqueous zincate solutions consist of mixtures.〔Glenn O. Mallory, Juan B. Hajdu, (1990), Electroless Plating: Fundamentals and Applications, American Electroplaters and Surface Finishers Society, , William Andrew Inc., ISBN 0-936569-07-7〕 ==Hydroxyzincates== Solutions of sodium zincate may be prepared by dissolving zinc, zinc hydroxide, or zinc oxide in an aqueous solution of sodium hydroxide. Simplified equations for these complex processes are: :ZnO + H2O + 2 NaOH → Na2Zn(OH)4 :Zn + 2 H2O + 2 NaOH → Na2Zn(OH)4 + H2 From such solutions, one can crystallize salts of containing the anions Zn(OH)42−, Zn2(OH)62−, and Zn(OH)64−. Na2Zn(OH)4 consists of tetrahedral zincate ion and octahedral sodium cations.〔Synthese und Kristallstruktur von Na2Zn(OH)4, R. Stahl , R. Niewa , H. Jacobs, Zeitschrift für anorganische und allgemeine Chemie, volume 625, pp. 48 - 50, 〕 The salt Sr2Zn(OH)6 features zinc in an octahedral coordination sphere. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Sodium zincate」の詳細全文を読む スポンサード リンク
