氟在卤族元素中居首位,较氯更活泼。多数氟的化合物,对皮肤均有腐蚀作用,而氟氢酸的腐蚀性是最强的一个。 氟氢酸能溶解硅及其盐类,因此被广泛应用于玻璃,陶瓷业,以及地质、冶金的矿样分析。由于碳氟化合物结构具有特殊稳定性和氟氢酸对某些有机化合物的特殊催化作用,从而获得 Fluorine ranks first in the halogen element, more active than chlorine. Most fluorine compounds have a corrosive effect on the skin, and the corrosiveness of hydrofluoric acid is the strongest one. Hydrofluoric acid can dissolve silicon and its salts, it is widely used in glass, ceramic industry, and geological, metallurgical mineral sample analysis. Due to the special stability of the fluorocarbon structure and the special catalysis of hydrofluoric acid on certain organic compounds,
