【Know Tungsten】Sodium Tungstate Applications

-
Sodium tungstate, Na2WO4•2H2O, a tungstate of sodium, is useful as a source of tungsten. It is prepared from tungsten ores to manufacture tungsten by reducing it. It is often found as dihydrate.

Sodium tungstate is an inorganic inhibitor. It has many advantages, such as low toxicity, no harm to environment, human body and crops, and no microorganism breeding. However, sodium tungstate has its unavoidable defects. First of all, the effect of single sodium tungstate is limited, and it needs to be used to enhance the effect, at the same time, sodium tungstate is more expensive and impractical to use. Therefore, more enterprises are using sodium tungstate and cheaper chemicals to make sodium tungstate composite corrosion inhibitor to realize the function of protecting metal. Polyaspartic acid (PASP) is a newly found environmental friendly water treatment agent. It has excellent scale inhibition, dispersion and good biodegradability, after polyaspartic acid used efficiently, stably microorganisms, fungi degradation of the final product harmless to the environment, is a very desirable water treating agent. What is the effect of combining sodium tungstate with pol...

Nanocrystalline cemented carbide is a tool material developed in recent years. It is based on nano tungsten carbide powder . The cemented carbide with high hardness, high wear resistance and high toughness has been produced under the condition of adding proper binder and grain growth inhibitor, its performance is obviously higher than that of conventional cemented carbide. It has been widely used in hard metal materials, cutting tools, micro drills in the electronics industry, precision molds, medical fields and other fields. In the aspect of ultrafine or nanocrystalline cemented carbide, there are only a few countries in the world such as the United States, Japan, Sweden and so on, which can produce alloy with both high hardness (HRA>90) and high strength (>3 200 MPa). The main difficulties come from ultrafine and nano tungsten carbide powder and other raw materials and cemented carbide production process. From 70 to 80s in China began to study the industrial pr...

The ITER device is a superconducting tokamak can produce large-scale nuclear fusion reactions,  aims to create a clean and sustainable energy future of mankind. ITER uses deuterium and tritium to produce nuclear fusion. Deuterium and tritium fusion in the circulation with millions, tens of millions of billions of temperature, the circulator must be strengthened by high temperature resistant metal, from the engineering point of view, material problems determine the success or failure of fusion energy development. In fusion materials, a very important type of material is plasma facing material (PFMs), and the general requirement for PFMs is: high temperature resistance, low sputtering, low hydrogen (tritium) retention and compatibility with structural materials. Tungsten is considered to be the most promising PFMs material, which can meet many requirements in this harsh environment. However, tungsten is facing severe brittleness because of its own structural characteristics. Therefor...
