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 extension 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, over titanium has the harder the more processing features, the typical specialist milling technology can not be scraped. 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 course 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 worthwhile, many researchers have been searching for alternative processes., More representative of the Cambridge process uses electrolysis to stable production of titanium brush. Armstrong process through trim 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 rub. However, only Cambridge process technology of the production of titanium swab is R & D, funded by the producers of titanium clean. So, compared to the other three processes for the production of titanium powder, its industrialization process easier. Nevertheless, experts vocal the Cambridge technology has been commercialized for many years, but it is still subject to hanging technical barriers choke. At the identical time, the other three processes of industrialization is also far from the example one. Armstrong process has been used to produce a small amount of titanium powder. But until now it has not been used in huddle production, there is reposing some volume from the commercial production of pocket money powder ( FCu ). Some people suspect that the MER process has some abeyant, but is reposeful in cardinal development, its outlook remains unconfirmed. The prompt spot, the hydrogenation dehydrogenation process most hoping, and is seeking financing to progress its production, experts credit that this process a few years succeeding to the production of titanium plate for the U. S. Army. However, just to its low - cost advantages are mostly from the high utilization of titanium rumble, the process standstill can not fully replace the Kroll process.
Research and development of Chinese titanium powder processing technology seems pay more attention on market and industry belief. 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 immense area applications. Nano - titanium powder preparation by a unique process that allows ordinary distemper, enhanced a new indolent - resistant, chafe 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, immense area applications. In addition, do the twin way, but also copper, strong, 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 purified 12 tons of nano metal powder, and performance improvements to improve significantly increase the cost much.
