Tungsten ore

  • Mosten
  • 20 May

The deposit is related to the second and three-stage magmatism in the early and third stages of the Yanshanian. It is known that the mineralization is mainly in the second-stage intrusive fine-grained granitic and third-stage intrusive fine-grained granites. The two-stage intrusive rock is produced by irregular rock or rock, and partly in the form of a dike-like output, and the multiple stages of the magmatism result in the complex structure of the rock mass and the superposition of the mineralization. The third stage of the intrusion of fine-grained granite, in addition to the tungsten ore, is associated with mineralization and mineralization. The ore minerals mainly include wolframite, scheelite, genectite, goethite, black and rare gold deposits, and other rare earth minerals. The ore has a fine grain structure and a compact and massive structure. The useful minerals are disseminated in the form of disseminated or fine-vein.

Welding method of stainless steel and molybdenum

  • Mosten
  • 13 May

Because the physical properties of molybdenum and its alloy are very different from stainless steel, there will be many problems in the welding process. In their welding, when heated to 400 ℃, a slight oxidation occurs, and when above 600 ℃, they rapidly oxidize to MoO3 compounds. The solubility of oxygen in molybdenum is very small. When the oxygen content increases, the oxide precipitates along the grain boundary, and the brittleness of other impurities is also precipitated, which makes the welding difficult. When molybdenum and stainless steel are welded, the high hardness and brittleness zone is easy to appear near the side of molybdenum base metal, the width of which is generally 0.5 ~ 3 mm.

Despite the numerous advantages of tungsten argon arc welding, almost all metals can be welded! However, there are two aspects of all things, and he also has shortcomings. Specifically, because of the poor wind resistance, the welding pool with argon gas is used to protect the weld pool during the welding process. If there is a velocity of air exceeding 5mil/h during the welding process, Argon shielded gas will be blown away, which immediately infects the weld area, resulting in porosity of the weld.

What metal is more resistant to tungsten than tungsten? Do you have a material with a melting point of 10,000 degrees?

  • Mosten
  • 29 Mar

Of all the metallic elements of the periodic table, tungsten has the highest melting point, with a melting point of 3422 ℃ (boiling point is 5930 ℃), and no metal element has a higher melting point than tungsten. The reason the melting point of tungsten is very high is related to the metal bond whose bond energy is very high. Tungsten is element 74, located in the sixth cycle of the VIB family in the periodic table. Among the congeners of tungsten, they have the largest number of valence electrons in metal elements, up to six, which means that each atom can form six metal bonds, so the bond energy of this group of elements is extremely high, resulting in a very high melting point.

Beware of heavy metal pollution! Tungsten deposits in water can have a "negative" effect on human bones

A team of scientists from the university of Chicago have published a new study in the journal Nature. They believe that tungsten may pose health risks to people, especially tungsten dust and tungsten-containing drinking water, which need to be taken seriously. Previously, tungsten was thought to pose little or no health risk to the general population. Tungsten itself is not toxic, but studies have found that when dissolved in water is ingested by the body and stored in the bones, it produces a chemical similar to phosphor tungstate, which is difficult to remove and can increase the toxicity of other metals ingested.In particular, in some areas where tungsten is mined, it is not uncommon to find sources of water with high levels of tungsten. Long-term consumption of such surface water or groundwater may pose health risks.

In nature, molybdenum mainly exists in the form of molybdenite (MoS2).Natural molybdenite is a soft black mineral, and while molybdenite has been used since ancient times, it is indistinguishable from lead, galena and graphite.The word "molybdos" means lead in Greek.Until the late 18th century, both were sold as molybadenite in European markets.

Tungsten alloys are made of highly conductive copper and refractory tungsten.The metal tungsten and copper neither dissolve each other nor form intermetallic compounds, but only form false alloys. Therefore, w-cu alloy presents the comprehensive excellent properties of tungsten, such as high temperature resistance, high hardness, low expansion coefficient, high thermal conductivity, electrical conductivity, good plasticity and so on.Due to their high resistance to arc ablation, welding, impact and mechanical strength, they are widely used in environments with high corrosion and wear.

In the metallurgical industry, molybdenum is used as an additive in the production of various alloy steels, or as a senior alloy with tungsten, nickel, cobalt, zirconium, titanium, vanadium, rhenium, etc., to improve its high temperature strength, wear resistance and corrosion resistance.Molybdenum-containing alloy steel is used to make transportation devices, locomotives, industrial machinery, and various instruments.Certain stainless steels containing 4 ~ 5% molybdenum are used for the production of precision chemical instruments and equipment used in seawater environments.High speed cutting tools can be made from 4% ~ 9.5% high speed steel.Alloys of molybdenum, nickel and chromium are used in the manufacture of metal components for aircraft, and corrosion resistant parts for locomotives and automobiles.Alloys of molybdenum and tungsten, chromium and vanadium are used in the manufacture of alloy components and parts for warships, tanks, guns, rockets and satellites.

Tungsten products and health protection

  • Mosten
  • 17 Jan

Tungsten is a very stable metal element, which is often found in various minerals in nature, but its properties are very stable. Tungsten compounds are harmful to human health. With the continuous expansion of the production scale of tungsten and its products, the use scope of tungsten is becoming wider and wider, and the potential threat of environmental pollution by tungsten is also on the rise. As a substance that can affect the chemical changes in the body and disrupt the biochemical exchange channels, the influence of tungsten on human health should also be paid attention to.
