The world in which a nation's largest tungsten reserves, yield the most? That is,we China. China has found a tungsten deposit in early tenth Century, at that timecalled it "heavy". Tungsten is widely distributed in China, South Central, North China, northwest and southwest have output, especially in the west of Guangxi,via Hunan, Guangdong, Jiangxi provinces, east to Fujian Nanling tungsten minearea, the most. Jiangxi is known as "tungsten". The southern part of Jiangxi province is as everyone knows the "tungsten Xiang", the size of tungsten mineshave hundreds, many Mountain Dew tungsten bearing quartz veins, West Huashan, Dajishan, Pangu mountain are world famous tungsten mine. With the development of the cause of socialist construction, Jiangxi in Jiangxi Gannantungsten origin to extend to the province by. A long time ago, tungsten output in China reached the world's total output of more than 70%.
As the saying goes: "the fire is the test of gold." In fact, really afraid of fire is not gold, but tungsten. In the steelmaking furnace hot, when the temperature reached 1600 degrees, the hard iron and steel will be molten steel into the boiling, gold will become a flowing liquid, but tungsten is still there, still solid.Tungsten melting point of 3410 DEG C, high boiling point of 5927 DEG C, the melting and boiling points of it, is the highest in the metal. In the iron and steel production, it is indispensable to add material. Its compounds used to dye, paint and chemical reagents. In recent years, tungsten is also added to the advanced science and technology in the fields, such as the incorporation of silver and 10 -15% of tungsten fuel nozzle can be used for the manufacture of rocket.
