2, Ningxia East non ferrous aiming at the international market to open up new areas of application of tantalum niobium beryllium


Entrusted by the State Ministry of science and technology, Department of science and technology of Ningxia


 Autonomous Region recently organized experts, of Ningxia Oriental nonferrous metals group company belongs


 the Northwest Institute of rare metal materials "superconducting cavity with niobium sheet production 


technology development" project was acceptance of the scene. The project is for the total investment of 3 


billion 500 million U.S. dollars, the energy level of the world's largest Superconducting Linear Accelerator


 for the development of Superconducting Linear Accelerator engineering technology research an development. Superconducting Linear Accelerator project is a multinational cooperation projects, built in Hamburg, 


Germany, total length of 33 km, the project needs to consume about 500 tons of niobium sheet. After the 


completion of the project, will greatly promote the physics, chemistry, materials science, environment and


 Earth Sciences, structural biology, and many other areas of science and technology progress, can solve the problem of nuclear waste disposal.



Experts believe that the superconducting cavity using niobium sheet production technology research and 


development success, open up the new application fields of niobium metal in China, to fill the gaps in this research in our country, make our new material manufacturing technology with international practice. 


Through participation in international cooperation projects, so that the formation of high-tech products in the diversification of tantalum powder, tantalum, tantalum strip and tantalum products and superconducting tantalum materials in Ningxia, and full range into the international market, China's Tantalum and niobium in the world top three position stability.


By "superconducting cavity niobium sheet production technology development" project implementation, the 


Northwest Institute of rare metal materials formed stable performance of superconducting niobium plate 


manufacturing technology, in the control of impurity elements, control residual resistivity, grain size


 control, yield strength and hardness control aspects made innovative achievements. To reach the 


international advanced level in manufacturing technology, product performance, become the material basis of


 the linear accelerator.



As a set of scientific research, production and technology development as one of the domestic largest 


tantalum, niobium products production base and only beryllium research and production base - Ningxia 


based on independent innovation, to achieve innovation and development.



In recent years, they after continuous independent research and development and technical research developed a number of tracking international developments, leading technology, new products to meet market demand at home and abroad, to achieve the tantalum powder, tantalum wire of high grade and technology improvement.


 Its flagship product, tantalum powder and application level in the market has reached 70000 volume and 


research level reached more than 15000 volume and entered into the leading ranks. Their research and 


development of new products, semiconductor with tantalum niobium target, nickel hydroxide, magnesium


 alloy and processing materials such as, has become to promote a new bright spot of economic growth in 


Ningxia. At present, the company has a total of 14 national patents, 3 international patents. Last year, the


 Ministry of science and technology formally approved the "national grade tantalum niobium special metal


 materials engineering technology research center  is group company established "the Ningxia Hui Autonomous Region International Cooperation in science and technology demonstration base".



In recent years, they focus on strengthening the combination, innovation team building, provide strong 


support for the development of enterprise technology. They and Nankai University jointly "lithium niobate


 crystals and devices research and Development Association, and Beijing University of science and 


technology jointly" homogeneous reduction method preparation of nanometer powder of room, and Tsinghua


 University jointly "beryllium welding technology research laboratory, has made substantial progress. 


At the same time, the postdoctoral workstation, national engineering centers, enterprise technology center 


platform to attract with strong technological innovation talents to carry out joint research and has made


 breakthrough progress in the "beryllium material inner stress of" and "deuterated beryllium and beryllium hydride of preparation technology research,".


In addition, they also with the Russian Light Alloy Research Institute established relations of cooperation, the introduction of magnesium alloy smelting and casting technology and some key equipment, through digestion and absorption, the construction of an annual output of 10000 tons of magnesium alloy and processing production line. 


The superconducting cavity with niobium sheet production technology development "project is good 


cooperation with German electron synchrotron research, the success and acceptance of the technology, enhance


 the metal niobium in China's technological level and production capacity, to enter the international 


market for China's metal niobium and processing materials lay a solid technology and market infrastructure.
