前言 海绵钛是采用TiCl_4生产的。由于钛具有许多众所周知的优良综合性能,使钛成为有发展前途的新型结构金属材料,被广泛用于航空、航天、化工、石油、轻工、冶金、能源、交通、海水淡化、造船和医药等各工业部门。有人说:“钛从空中金属开始,70年代末确立了地上金属的地位,而80年代作为海上金属也将开始”。这反映了钛被应用的广度和发展趋势,向人们预示,21世纪将是钛的世纪。钛的资源分布很广,几乎遍布全世界。已知含钛1%以上的矿物有80多种,但目前世界钛工业原料仅有金红石、钛铁矿和钒钛磁铁矿等数种。
Preface Titanium sponge is produced using TiCl 4. Titanium is a promising new structural metal material because of its many well-known, well-integrated properties. Titanium is widely used in aerospace, aerospace, chemical, petroleum, light industry, metallurgy, energy, transportation, desalination, shipbuilding and medicine. Various industrial sectors. Someone said: “Titanium begins with the metal in the sky and has established the status of above-ground metal in the late 1970s, and it will also begin as an offshore metal in the 1980s.” This reflects the breadth and trend of application of titanium, which indicates to people that the 21st century will be the century of titanium. Titanium resources are widely distributed, almost all over the world. Known more than 1% of titanium containing more than 80 kinds of minerals, but the world’s only titanium industry raw materials rutile, ilmenite and vanadium titanomagnetite and other species.
