产钨最多的国家——中国

  世界上哪一个国家的钨储量最大、产量最多呢?那就是我们中国。我国早在10世纪就发现了钨矿,当时称它为“重石”。钨矿在我国分布很广,中南、华北、西北和西南都有产出,尤其是在西起广西,经湖南、广东、江西三省,东到福建的南岭一带,钨矿最多。江西被人们誉为“钨都”。江西省南部则是众所周知的“钨乡”,大小钨矿山就有数百处,很多山头都露含钨石英脉,西华山、大吉山、盘古山等都是世界有名的钨矿山。随着社会主义建设事业的发展,江西钨矿产地以由赣南扩及赣中以至全省。很早以前,中国的钨产量就达到世界总产量的70%以上。

  俗话说:“真金不怕火炼。”其实,真正不怕火的不是金,而是钨。在炽热的炼钢炉里,当温度达到1600℃时,坚硬的钢铁都会化成沸腾的钢水,金子也会变成流动的液体,而钨却纹丝不动,仍是固体。钨的熔点为3410℃,沸点高达5927℃,它的熔点和沸点,在金属中都是最高的。在钢铁生产中,它是不可缺少的添加料。它的化合物用于染料、油漆和化学试剂。近些年来,钨还加入到尖端科学技术领域,如掺入银10-15%的钨,可用来制造火箭的燃料喷管。

  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.
