应用

Sputtering is a process whereby atoms are ejected from a solid target material due to bombardment of the target by energetic particles. The extreme miniaturization of components in the semiconductor and electronics industry requires high purity sputtering targets for thin film deposition.

Tungsten is a widely used transition metal that has not been thoroughly investigated with regards to its ecotoxicological effects. Tungsten anions polymerize in environmental systems as well as under physiological conditions in living organisms. These polymerization/condensation reactions result in the
