2.13 阻燃剂锑用于制造以三氧化二锑为主要形式的阻燃剂。也可采用氯氧化锑、锑酸钠和五氧化二锑作阻燃剂。五氧化二锑比三氧化二锑昂贵,它的应用多限于那些对其性能的特别要求胜过高成本这一缺点的地方。含三氧化二锑约5O％的硅-锑复合物也时有被用来作阻
2.13 Flame Retardant Antimony is used in the manufacture of flame retardants, mainly in the form of antimony trioxide. Antimony oxychloride, sodium antimonate and antimony pentoxide can also be used as flame retardants. Antimony pentoxide is more expensive than antimony trioxide, and its use is limited to those places where the special requirements for its performance outweigh the high costs. Antimony trioxide with about 5O% of the silicon - antimony compounds are sometimes used to make resistance
