Tungsten target, also known as tungsten sputtering target, is a product made of pure tungsten powder, with a silver-white appearance, and is popular in many fields because of its excellent physical and chemical properties.
Tungsten sputtering target production process:
It is generally prepared by the powder metallurgy method. First, put the tungsten powder in a vacuum heat treatment furnace for pre-degassing, then introduce hydrogen, and continue heating for degassing; second, sinter the degassed tungsten powder through vacuum hot pressing; third, put the tungsten powder once The sintered product is subjected to secondary sintering by a hot isostatic press; fourthly, the entire surface of the sintered product is machined and ground to obtain the product.
Note 1) The purity of tungsten powder should be more than 99.999%, and the particle size should be between 3.2-4.2μm.
Tungsten target application:
Widely used in flat panel displays, solar cells, integrated circuits, automotive glass, microelectronics, memory, X-ray tubes, medical equipment, smelting equipment, and other products.
Baoji Yusheng Metal Technology Co., Ltd. hereby reminds everyone that the purity, density, microstructure, internal quality, welding quality, appearance quality, and geometric size of the tungsten target have an important impact on the quality of the coating, and look forward to purchasing.
