Tungsten for Sapphire Growth and LED Disc

 For the hot seller of iphone series, including iphone4, iphone4s, iphone5, iphone 5s, and recently iphone6 and iphone6s, the screen of iphone phones has been very important, and also brought the world a new opportunity to manufacture LED disc. With this idea, the intermedia to grow sapphire, which has been the materials for LED sheet, has moved to tungsten and molybdenum because of its high purity and high temperature resistance.

 Tungsten materials used in sapphire growth furnace range from tungsten wire, tungsten rod, tungsten crucible,  tungsten bar, and others. Tungsten crucible has been the most important part for its direct touch of LED sheet.  Tungsten sheet has been designed to resist temperature from spreading.

How to Prevent Broken Tungsten Crucible Bottom

 During application of tungsten crucible, the broken of tungsten crucible bottom will lead to the whole set can not work. Therefore, methods should be used before applying, and during manufacturing. After shaping tungsten crucible out from mold, the pressure for shaped should control well, so that the crucible can have a good inner structure. Then sintering, the time and temperature have been very important. These two factors will influence the whole set of crucible, such as there is some breaks or crack on the crucible, they mostly occur in this period.

 Grounding is the last step, the attention point is be careful during processing to keep the crucible in good situation.

 Method to prevent tungsten crucible from breaking during transportation is to use thick and hard outer packing material and soft inner ones.

Spring Festival Approaching, Tungsten Price Rose Slowly

With the coming of  Chinese Spring Festival, tungsten market in China is reluctant to sell the whole mood darker, more domestic tungsten smelter production orders, shipments active low, slow rise in the overall price of tungsten, but the terminal needs to improve Write, tungsten prices rose weakness.

Currently the mine is still at a relatively low price, the latter even without price increases, more limited declines, the risk of hot money into the tungsten and now the city is relatively small, so the traders and the hot money is still on active inquiry, Scheelite intends store point of shipment, the coming year make the difference. Since the terminal demand is still sluggish, really large inventory of raw materials Scheelite history, it is expected before the Spring Festival tungsten concentrate prices rose fatigue, post or continue to firm, still was up possible.

World's Largest Tungsten Mine Found In Jiangxi

From the 21st of Jiangxi Bureau of Geology 2015 work meeting was informed that in 2014 the council in Jingdezhen Fuliang County Zhu Xi proven tungsten copper project, or to refresh the record of the world's largest reserves of tungsten deposits.

According to the Jiangxi Provincial Bureau of Geology and Mineral Pengze Zhou introduced in 2014, the council continues to make in copper, tungsten, iron, lead, zinc, rare earth, fluorite, kaolin, geothermal and other important minerals exploration breakthrough, proven or initial proven large deposit size 6, 11 medium-sized deposits, small deposits 21, the potential economic value of 105 billion yuan.

Pengze Zhou said, Jingdezhen Fuliang County, Zhu Xi tungsten copper tungsten portion of the project has proven reserves of more than 1 million tons, 300,000 tons of copper resources, and good exploration prospects, high grade, or to refresh the world's largest reserves of tungsten deposits record. In Jiujiang and Ruichang two copper exploration is expected to be submitted to the amount of 1.5 million tons of copper resources, Jiangxi Copper ore nearly 30 years the best results.

Jiangxi is China's famous "non-ferrous metals town", excellent condition mineralization. Following a few years ago, Jiangxi discovered and 1.06 million tons of proven world's largest tungsten mine that big after wuning HUTANG tungsten ore, tungsten copper Jingdezhen Fuliang Zhu Xi is a large tungsten copper project in Jiangxi Bureau of Geology and Mineral Resources found again.
