What is tungsten hexachloride? Tungsten hexachloride is the chemical compound of tungsten and chlorine with the formula of WCl6. It shows dark blue or blue violet appearance, and exists as a volatile fine powder under standard conditions. More details, please visit: http://tungsten-hexachloride.com/index.html Tungsten hexachloride is a blue-black solid at room temperature. At lower temperatures, it becomes wine-red in color. A red form of the compound can be made by rapidly condensing its vapor, which reverts to the blue-black form on…

Tungsten carbide milling tool, also called tungsten carbide milling cutter, is a cutting tool typically used in milling machines or machining centers to perform milling operations. It removes material by its movement within the machine or directly from the cutter’s shape. It is mainly used for machining planes, steps, grooves and forming surfaces on PCB boards, bakelite boards, plastics, wood, etc. Well, do you know why tungsten carbide milling tool breaks?

High purity ammonium metatungstate is a water soluble crystalline powder with white or yellowish appearance. It is an important intermediate compound in the tungsten wet smelting process. Also, it is one of tungsten catalysts. The active component of ammonium metatungstate (AMT) catalyst is tungsten trioxide (WO3), which is used as a catalyst carrier. With the vigorous development of the petroleum processing industry, the research, development and application of high purity ammonium metatungstate have also been directly promoted. More details, please…

Here is a filter unit for ammonium metatungstate concentrated solution. It is reported that impurities will exist in the ammonium metatungstate solution, affecting the quality of the AMT solution and ultimately the quality of the prepared AMT powder. However, the existing filter unit for ammonium metatungstate concentrated solution has the problems of low filtration efficiency, easy leakage during storage and inconvenience to clean up the leaked ammonium metatungstate solution. Therefore, it is very necessary to invent a multidingal AMT concentrated…

How to prepare ammonium metatungstate? The researchers have proposed a preparation method of ammonium metatungstate – mainly used as a catalyst for petroleum cracking. More details, please visit: http://www.ammonium-metatungstate.com/index.html A Preparation Method of Ammonium Metatungstate Step One: Dissociation. 100kg of APT is heated and calcined in the rotary furnace at a temperature of 180°C for 50 min to prepare a dissociated material. At the same time, the inlet of the rotary furnace was fed with rare gas helium gas, the…

Ammonium metatungstate (AMT) is one of the most important raw materials and precursors for preparing tungsten carbide catalyst. The physical and chemical properties of AMT affect the structure and performance of the prepared tungsten carbide (WC). The particle size and structure of the precursor will have a greater impact on the later reduction carbonization process, which in turn will affect the catalytic activity of the tungsten carbide catalyst, according to the researchers.
