Characterization of Nanometer Tungsten Powder

Three types of nanometer tungsten powder were prepared by hydrogen reduction of three precursor powders at low temperatures, which were used as examples and were characterized by Brunauer-Emmer-Teller (BET) method, scanning electron microscopy (SEM) microscopy transmission electron microscopy (TEM),

How are metal powders maked?

The first step in the overall PM process is making metal powders. There are four main processes used in tungsten powder production: solid-state reduction, atomization, electrolysis, and chemical.

What is Tungsten Carbide?

Tungsten carbide is sometimes colloquially referred to as simply "carbide." Its general definition is described as: Tungsten carbide is an inorganic chemical compound which contains equal numbers of tungsten and carbon atoms. It is also caled tungsten cemented carbide. Tungsten cemented carbide can be pressed and formed into shapes from fine gray powder, which is considered to be its most basic form. The applications of tungsten cemented carbide are widely reflected in industrial machinery, wear resistent tools, abrasives as well as men' s jewelry.

As medical science developing so repaid, there is more and more radiation in our life, which has become a new trouble, such as X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc. Tungsten alloy radiation cap protect us from the radiation. Tungsten alloy radiation shielding is better than shielding made by other materials.

Tungsten alloy ,also named tungsten heavy alloy, generally is refractory metal, which have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloys are added Co、Mo、Cr, etc. They have very high melting point and have a density twice that of steel and are more than 50% heavier than lead. Tungsten content in conventional heavy alloys varies from 90 to 98 weight percent and is the reason for their high density (between 16.5 and 18.75 g/cc).

The price of tungsten granule has been going up as the price of raw material has been increasing since October. Recently, quotation of tugnsten granule is USD75.00/KG.
