The reduction of the melting point from approximately 3600 K to 8 Oct 2020 Optical properties of tungsten trioxide, palladium, and platinum thin films for functional nanostructures engineering.

Tungsten, rhenium, osmium, tantalum, and molybdenum are among the highest melting point metals. Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces. Tungsten products are made from tungsten powder and not through the conventional manufacturing process of melting and casting. This is due to the powders extremely high melting point. This technology is called tungsten powder metallurgy and consists of pressing powder into parts, sintering and then machining to the desired form.

W is a d-block metal from the 3 X r d row which make it possible to have covalent materials rather than ionic materials. Tungsten has the highest melting point of all the refractory metals, a low coefficient of thermal expansion and a relatively high density. Tungsten's good electrical conductivity and excellent thermal conductivity are further valuable properties.
