According to this source, an alternative pronunciation of the second word is and, in the UK, also .〕 is an inorganic chemical compound with the formula NaF. A colorless solid, it is a source of the fluoride ion in diverse applications. Sodium fluoride is less expensive and less hygroscopic than the related salt potassium fluoride. ==Structure, general properties, occurrence== Sodium fluoride is an ionic compound, dissolving to give separated Na+ and F− ions. Like sodium chloride, it crystallizes in a cubic motif where both Na+ and F− occupy octahedral coordination sites; its lattice spacing, approximately 462 pm, is somewhat smaller than that of sodium chloride. The mineral form of NaF, villiaumite, is moderately rare. It is known from plutonic nepheline syenite rocks. 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 fluoride」の詳細全文を読む スポンサード リンク
