Pure Tungsten Metal Sputtering Target
Description:
Tungsten sputtering target is a product made of pure tungsten powder as raw material. It has a silvery white appearance and is popular in many fields because of its excellent physical and chemical properties.
Sputtering targets are used for magnetron sputtering coating, which is a new type of physical vapor coating (PVD) method.
An orthogonal magnetic field and an electric field are added between the sputtered target and the anode, and the required inert gas (usually Ar gas) is filled in the high vacuum chamber. Under the action of the electric field, the Ar gas is ionized into positive Ions and electrons, a certain negative high voltage is added to the target. The electrons emitted from the target are affected by the magnetic field and the ionization probability of the working gas increases, forming a high-density plasma near the cathode. Ar ions are driven by the Lorentz force. It accelerates to the target surface and bombards the target surface at a very high speed, so that the sputtered atoms on the target follow the principle of momentum conversion and fly away from the target surface with high kinetic energy to the substrate to deposit a film.

Application:
Tungsten targets have the following advantages:
1. The widespread application of powder metallurgy makes the cost of tungsten targets lower than the costs of other target materials, such as titanium;
2. The composition and structure are uniform, which improves the deflection force of the tungsten target;
3. The particle size is fine, the grains are uniform and equiaxed, the concentration is high, and the coating product quality is high.
