1. Introduce – Rhenium is a refractory metal primarily used as a material for manufacturing superalloys capable of withstanding high temperatures – It is a metal with a high melting point (3,180°C) and boiling point (5,590°C) – Rhenium alloys can be used as superconductors at extremely low temperatures – Compared to other metals, it has relatively low chemical reactivity, so it does not oxidize easily in air; however, in humid atmospheres, its surface oxidizes and discolors at a slow rate (powder forms are relatively more reactive) 2. Application & Product – A...
