Description of key information

Tungsten is a solid metal with a grey-white color with a melting point range between 3390 and 3423°C, and a boiling point ranging from 5555 to 5700°C; with a relative density between 19.25 -19.35 g/cm³. Tungsten metal has a low water solubility of 16.51 mg W ion/L (at a loading of 100 mg/L and pH of 8.5) as determined by the transformation/dissolution study, and a particle size distribution (D50=6.6µm) in the micro-sized range . Vapor pressure of tungsten metal is expected to be extremely low at ambient temperatures.
