R & D Of Chinese Titanium Powder Technology Gets Remarkable Achievements

With the rapid development of science and technology in recent years, more and more titanium and titanium alloy powder is widely used in various high - tech fields, industrial production and people ' s lives. The international demand is also growing. The market prospects are very broad. Especially the United States and Japan has constant upping in demand for titanium. Chinese titanium annual demand is about 2. 5 to 3 million tons and Chinese annual titanium production is only 1, 500 to 2, 000 tons. There is a huge gap in the market.
However, because titanium has the harder the more processing features, the run-of-the-mill scientific milling technology can not be grazed. Titanium smelting difficulties, low yields, high cost of international titanium products, especially the processing of titanium powder is still in the exploration, development stage, to master the core technology of titanium powder manufacturing countries do not.
Of the most common shortcut of extraction from the ore of titanium, the Kroll process. However, due to the Kroll process to produce a long time, labor and energy are more worthy, many researchers have been searching for alternative processes., More representative of the Cambridge process uses electrolysis to matching production of titanium brush. Armstrong process through common low - temperature reduction of titanium tetrachloride to produce titanium powder. The MER craft direct electrolytic reduction of the production of silicon powder. Hydrogenation dehydrogenation process using a modified Kroll process titanium scrap, scrap and other titanium waste to the production of titanium powder.
There are three kinds of titanium powder production process. One of them is for titanium clean. However, only Cambridge process technology of the production of titanium mop is R & D, funded by the producers of titanium rub. For, compared to the other three processes for the production of titanium powder, its industrialization process easier. Nevertheless, experts verbal the Cambridge technology has been commercialized for many years, but it is still subject to unsettled specialized barriers barricade. At the twin time, the other three processes of industrialization is also far from the ideal one. Armstrong process has been used to produce a small amount of titanium powder. But until now it has not been used in corral production, there is windless some seat from the commercial production of pennies powder ( FCu ). Some people vision that the MER process has some abeyant, but is reposing in initial development, its outlook remains debatable. The instant site, the hydrogenation dehydrogenation process most expectant, and is seeking financing to ripe its production, experts lap up that this process a few years sequential to the production of titanium plate for the U. S. Army. However, becoming to its low - cost advantages are mostly from the high utilization of titanium dogfight, the process rural can not absolutely replace the Kroll process.
Research and development of Chinese titanium powder processing technology seems pay more attention on market and industry nut. They achieved remarkable results. In 2000, the subject of the preparation and application of titanium nano - scale metal powder identified by the relevant departments and goodly area applications. Nano - titanium powder preparation by a unique process that allows ordinary emulsion, expanded a new dull - resistant, ulcer resistance and other performance, this achievement in an international initiative, with the majority of nanotechnology research is still in laboratory stage, the results have been the first to achieve mass production, goodly area applications. In addition, do the identical way, but also copper, compressed, nickel powder and other metal powders, nano - materials. Industrial prospects of this outcome have been shown to be very broad. Synchronization through the identification of high - performance grinder, stand - alone each year can be distilled 12 tons of nano metal powder, and performance improvements to improve significantly increase the cost much.
