Titanium sponge is the basic raw material for the production of refined metal titanium. The further refinement of titanium sponge, can be made of titanium ingots, titanium bar, titanium metal material. The sponge titanium by mechanical grinding, can produce titanium powder. Titanium powder as the coating material, is widely used for surface treatment processing machinery and equipment, electronics and precision instruments, and other metal can be synthesized titanium alloy powder etc.. The concept of another branch of titanium sponge titanium production on the stage, the titanium dioxide concept stocks, has become the focus of attention of the market. In the Western materials trading producing titanium sponge lead, also have the extraordinary performance. It is reported, authorities have to consider the introduction of policies, preparing for the implementation of access management of titanium sponge industry, without the technical characteristics obviously or duplicate construction projects during the 12th Five Year Plan period, will not be authorized. Sponge titanium production is the basic link of titanium industry, it is titanium, titanium powder and other raw materials of titanium component. The ilmenite becomes four titanium chloride, then put in a sealed stainless steel tank, filled with argon, making them react with the magnesium metal, get "titanium sponge". The porous, "sponge titanium" is not used directly, also must put them in an electric furnace melting into a liquid, in order to cast titanium ingot. Titanium industry chain from upstream rutile titanium concentrate, titanium,titanium sponge, to quote product of titanium, can more clearly see is currently occurring from the upstream industry chain and cost push price type promotion. Titanium dioxide is thought to be the world's best performance of a white pigment, widely used in paints, plastics, paper, printing ink, chemical fiber, rubber, cosmetics industry.
The titanium concentrate prices have hit a record and maintain the basic stability of titanium plate and titanium dioxide, shipment is basic and normal price increase, domestic titanium currently costs more difficult, suffered greater cost pressure. What is the titanium sponge? It is the sponge titanium production of metal thermal reduction method. % purity (quality) is generally 99.1 ~ 99.7. Impurity elements% (quality) a total of 0.3 ~ 0.9, impurity elements oxygen% (mass) of 0.06 ~ 0.20, hardness (HB) ranged from 100 to 157, according to the different purity of WHTiO to MHTi4 five grades. As the main raw material for the preparation of industrial titanium alloys. Sponge titanium production is the basic link of titanium industry, it is titanium, titanium powder and other raw materials of titanium component. The ilmenite becomes four titanium chloride, then put in a sealed stainless steel tank, filled with argon, making them react with the magnesium metal, get "titanium sponge". The porous, "sponge titanium" is not used directly, also must put them in an electric furnace melting into a liquid, in order to cast titanium ingot. From the discovery of Ti to first prepare the metal titanium relatively pure has experienced 120 years of history. By the lab for the first time to obtain the pure titanium to the first industrial production, has spent the past 40 years. Many researchers do a lot of exploration, from failed again and again, to produce titanium sponge tonnage.
Four titanium chloride is mainly used for the production of sponge titanium, titanium dioxide and titanium trichloride. Many of its preparation method, mainly in boiling chloride fused salt chlorination furnace, and 3 methods of chloride. Boiling chlorination is the main method of the current production of four titanium chloride (China, Japan, America use), followed by the molten salt chlorination (the CIS countries), and the shaft chloride has been eliminated. Boiling chlorination is generally low in calcium and magnesium content of high grade titanium rich material as raw material, and molten salt chlorination could use the materials containing high contents of calcium and magnesium.
