Researchers have found that trace impurities affect the properties of refractory metals in various ways.
The application of refractory metals in the microelectronics industry will increase day by day. Potential applications in future microelectronics devices depend heavily on the availability of refractory powders at 5N and 6N purity levels (i.e. 99.999 and 99.9999%). Now, some manufacturers have been able to produce this kind of high purity Mo, Nb, Ta, and W metal powder.
The recyclability of ferroalloys is the main reason for their appearance on the green materials list. This is especially true for electronics, where recycling is crucial to the conservation of the environment, and iron recycling can mitigate the ecological damage caused by mining new metals. Compared with other heavy metals, iron is the most environmentally friendly.
Eyeglass frames, jewelry and watches are just some of the many fashion applications for tungsten.
