June 29 , multi-composite and preparation of rare earth tungsten electrodes through the identification technology in Beijing , China Academy of Engineering left Tieyong , China Nonferrous Metals Industry Association vice president Niu due Jian, China Tungsten Industry Association president Zhou Juqiu other leaders and experts attended the appraisal. Tungsten is a kind of widely used welding, plasma welding, spraying, cutting technology and metallurgical industry in the critical heat source materials used annually worldwide total consumption of tungsten electrodes has reached 1,600 tons ( the highest melting point of tungsten metal fuel arc volatilization ) , development of market demand as the economy is still growing steadily. 
However, currently used in over 70% of the tungsten electrode is still contaminated with radioactive thorium tungsten electrode , serious pollution of the environment and harm to human health , workers in countries around the world working to develop alternative materials , but has not been fully replace thoriated tungsten electrodes industrial products . The project bears the national " 973", " 863 " and other topics to explore in the long-term accumulation of Beijing University of Technology , based on research cooperation, independently developed a comprehensive multi -performance composite rare earth tungsten electrode material and preparation techniques , in Beijing General Research Institute of Mining and Metallurgy Beijing tungsten & Molybdenum material Factory achieve the industrialization of the product by the National welding Material quality supervision and Inspection Center and users prove than the current element thorium tungsten and rare earth tungsten electrodes superior performance to meet the industry standards and requirements . Project research breakthrough material composition , manufacturing process and equipment, and testing equipment and other core technologies , the formation of 15 patented technologies and production technology standard system. Currently , the new multi- rare earth tungsten electrode tungsten and molybdenum products in the Beijing plant material to achieve a stable mass production and large-scale industry in the global market , applied to industry, agriculture , national defense and other fields. Since 2004, the sales revenue of 130 million yuan has been obtained obvious economic and social benefits.
Thorium tungsten electrode with current technology compared to the composition of the product design , manufacturing process , technical performance and environmental impact , etc. are prominent innovations and significant progress , the overall technological level of similar products abroad have been better . The full range of products with independent intellectual property rights successfully replaced radioactive tungsten electrodes , truly low-emission in the field , the development of non-polluting , can be applied to the field of TIG and plasma technologies in a variety of steel and non-ferrous metals , aluminum, copper , titanium such as welding , cutting, painting , smelting , involving a wide range of civilian and military industries ; industrialization of the project after the Beijing material industry to solve a major technical problems, improve China tungsten processing industry 's international competitiveness , and promote the technological progress and industrial structure optimization and upgrading .

Today, rare earth market weakness steady, the market demand for light , few inquiries . Recently purchased less because some loose oxides and metal prices down in the short term is likely to continue downward.
Currently gadolinium products market , less turnover , inquiries are not active, Baotou manufacturers that now gadolinium oxide with ticket prices have been at 185,000 yuan / ton, gadolinium- iron with a ticket price of 195,000 yuan / ton, compared with 9 prices were already obvious downside , there are no signs of demand against warm , afternoon , or continue to shock .
Yttria market , prices were unchanged in recent days , traders quoted in the 7.5-7.8 yuan / ton or so , the price is slightly down slightly from last week . Recent yttrium oxide, samarium and other less attention , samarium oxide have less purchasing inquiries , insiders reflect recent orders basically no samarium oxide , have less purchasing, market price of about 22,000 yuan / ton.
Due to the recent light rare earth market , praseodymium neodymium , dysprosium or related products market weakness , the downstream magnetic scrap market was also affected, today part of the magnetic electric car scrap recyclers price continued to fall by 1 yuan / kg, according to a recycling factory disclosed, bad bad market quotations are not willing receiving strong magnetic late scrap prices may continue to fall.
