Zinc borate is an inorganic compound, a borate of zinc. It is a white crystalline or amorphous powder insoluble in water. Its toxicity is low. Its melting point is 980 °C. ==Variants== Several variants of zinc borate exist, differing by the zinc/boron ratio and the water content: * Zinc borate Firebrake ZB (2ZnO·3 B2O3·3.5H2O), CAS number 138265-88-0 * Zinc borate Firebrake 500 (2ZnO·3 B2O3), CAS number 138265-88-0 * Zinc borate Firebrake 415 (4ZnO·B2O3·H2O), CAS number 149749-62-2 * ZB-467 (4ZnO·6B2O3·7H2O), CAS number 1332-07-6 * ZB-223 (2ZnO·2B2O3·3H2O), CAS number 1332-07-6 The hydrated variants lose water between 290–415 °C. 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「Zinc borate」の詳細全文を読む スポンサード リンク
