Tungsten (W)
- Description
Description
Tungsten is a steel-gray to silver-white metal. It is commonly used in the electrical, medical, and automotive and other industries.
High-purity tungsten and its silicides are used in ultra-large-scale integrated circuits as resistance layers, diffusion barriers, etc., as well as gate materials and connection materials in metal oxide semiconductor transistors
It is also applied to manufacture sputtering targets of Tungsten, Tungsten-Titanium and Tungsten-Silicon and to make evaporation materials in semiconductor applications.
