金属钛的制取方法（Method for producing metallic titanium） Metal titanium production method.Txt I have only two things in life, No: this will not, and that will not. Others have backgrounds, and I have back figures. The ideal of meat, the fate of cabbage. The ideal of meat, the fate of cabbage. White horse. Where have you been?! Did you lose the prince and dare not come to see me?. Method for producing metallic titanium Titanium and its alloy have excellent properties such as small density, corrosion resistance and high temperature resistance. The world titanium industry is experiencing a single mode of aviation and aerospace as the main market, to the metallurgical, energy, transportation, chemical, biological, pharmaceutical and other civilian areas as the focus of the development of multi mode transition. At present, only a few countries in the world, such as the United States, Japan, Russia, China and so on, can produce titanium industrialization. The total annual output of titanium is only tens of thousands of tons. But as a result of the strategic importance of titanium and its position in the national economy, titanium will become the third metal after the iron and aluminium, and the twenty-first Century will be the century of titanium. The current titanium production method, the current titanium production using metal heat reduction method, which refers to the use of metal reducing agent (R) and metal oxides or chloride (M, X) reaction to prepare metal M. The titanium metallurgy methods that have been industrialized production are magnesium reduction method (Kroll method) and sodium heat reduction method (Hunter method). Because Hunter is more expensive to produce than Kroll, Kroll is the most widely used method in industry. Since its development in 1948, Kroll has been criticized for its high cost and low efficiency. Half a century later, the process has not fundamentally changed, still intermittent production, failed to achieve continuous production. Method for prod
