How is the tungsten target produced?
What is Tungsten target?
Tungsten target, also known as tungsten sputtering target, is a product with pure tungsten powder as raw material. Its appearance is silvery white, and it is popular in many fields because of its excellent physical and chemical properties.

Production technology of tungsten target material
Generally, it is prepared by powder metallurgy. First, putting tungsten powder in a vacuum heat treatment furnace for pre-degassing, introducing hydrogen, and continuing heating for degassing; Secondly, the degassed tungsten powder is sintered once by vacuum hot pressing; Thirdly, the product sintered once is sintered twice a hot isostatic press; Fourthly, grinding the whole surface of the product after secondary sintering through mechanical processing to obtain the product. Attention: 1) The purity of tungsten powder should be above 99.999% and the particle size should be between 3.24.2 μ m.
Characteristics of Tungsten target
1) The purity is high, and the purity of the target after sintering and forging can usually be higher than 99.95%. Generally speaking, when other conditions remain unchanged, the higher the purity of the target, the better the electrical properties of the film, and the less likely the corresponding circuit will be short-circuited or damaged.
2) The cost is relatively reasonable, and the speed of direct pressing molding by powder metallurgy is faster, which can effectively shorten the production cycle and further reduce the cost.
3) The density is high, and the target density after sintering and forging can reach above 19.1g/cm3.
4) The deflection force is high, and the composition and structure of the target product produced by ultra-fine pure tungsten powder are uniform and consistent.
5) The thermochemical stability is good, and phenomena such as volume expansion or contraction and chemical reactions with other substances are not easy to occur.
6) The resistance is low, and the circuit will not generate unnecessary energy.
In addition, it has the characteristics of a high melting point, high elasticity, low expansion coefficient, low vapor pressure, and non-toxic and non-radioactive.
Uses of Tungsten target
Widely used in flat panel displays, solar cells, integrated circuits, automotive glass, microelectronics, memories, X-ray tubes, medical equipment, melting equipment, and other products.
Price of Tungsten target
Tungsten target particle size and purity will affect the price, and the purchase volume can also affect the cost of Tungsten target. A large amount of large amount will be lower. The price of Tungsten target can be found on our company's official website.
