Synthesis of Tungsten White in High Melting Point Rare Metals
The synthesis of tungsten white in rare high melting point metals is a complex process with its own unique set of challenges. With decades of development, this process has yielded a tungsten white product with a variety of design specifications and performance characteristics. It is important to understand the process to ensure a successful outcome.
Tungsten is a rare earth metal, which is a highly heat-resistant metal that can often be found embedded in rare earth ore or minerals. Such minerals are recovered by traditional methods like deep-sea drilling for the ocean bed. Tungsten is extracted from the ore by a process known as “reduction,” which involves heating ore until the metal is vaporized. The metal is then cooled and condensed into solid particles, which contain the metal in its elemental form.
Next, the solid particles are heated in a furnace to temperatures exceeding those used in redox reactions. This process is called “smelting.” At these extreme temperatures, the metal is transformed into a liquid form, which then enters a molten bath of other metals. This combination of metals is then formed into a wire rod and continuously cooled. This process is repeated until the desired properties of the tungsten white product are achieved.
Once the desired properties have been achieved, the tungsten white product is conditioned for use. This conditioning process is vital to ensure a consistent quality of the product. It involves removing impurities such as carbonaceous matter, which may affect the strength, malleability and other physical properties of the metal. This process also increases the consistency in the composition of the tungsten white product, which is important for predictable performance and use in a variety of applications.
To further ensure a consistent and controlled performance, the tungsten white product is quenched and tempered. Quenching is a process of rapidly cooling the metal by means of air or water. Tempering is the process of heating and cooling the metal at specific temperatures, which is used to create an ideal combinatio
