工业上从含钛物料制取钛的途径,主要是冶炼生产海绵钛。这种原生金属钛是具有多孔的海绵样结构,因而叫海绵钛。海绵钛的工业生产方法相当复杂,基本建设的投资也大。目前冶炼生产海绵钛主要有两种方法:一种是“钠还原法”或“亨特 Titanium industry from the preparation of titanium materials approach, mainly the production of titanium sponge smelting. This native titanium is a sponge-like structure with a porous structure, hence the name titanium sponge. Sponge titanium industrial production method is quite complex, capital investment is also large. There are currently two main methods for smelting titanium sponge: one is the “sodium reduction” or "hunt
