Tungsten evaporation boats

Tungsten has the highest melting point and lowest vapor pressure of all metals, and at the temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids.Tungsten is the most useful material used in vacuum evaporation technique, due to its special properties and cost factor.Properties of TungstenChemical symbol:WAtomic Radius:2.02?Atomic Volume, cm3/mol:9.53Covalent Radius:1.3?Crystal Structure:Body centered cubeNumber of Electron (with no charge):74Atomic Number of Protons:74Number of Neutrons (most common/stable nuclide):110Ionic Radius:0.62?Cross Section:...
