Whereas for fluorine, fluorine is smaller than f minus is the one that's the outer shell shown here.
而对于氟来说,氟原子更小,与外部壳层在这的负一价氟离子相比。
A halogen element, f, is major raw materials deriving fluorine compound, and because of low melting point, that is widely used in steelmaking, nonferrous metal smelting, cement, glass and ceramics.
萤石中含有卤族元素氟,是制取含氟化合物的主要原料,又由于熔点低而广泛用于炼钢、有色金属冶炼、水泥、玻璃、陶瓷。
The results show that the hydrogen of C—H bond on ACFs were substituted by fluorine at different condition. The C—F covalence bond was built at molecular level.
结果表明,随着反应时间和温度的变化,活性炭纤维表面氟取代氢基数目增加,同时在分子水平上形成C—F共价键。
