Dark-blue or violet hexagonal crystals,
volatile. Electrical conductivity (fused
state) poor. Soluble in organic solvents including
ligroin and ethanol; decomposed by moist air and
water; reduced by hydrogen to the metal.
Tungsten coatings on base metals, vapor deposition
for bonding metals, single crystal tungsten
wire, additive to tin oxide to produce electrically
conducting coating for glass, catalyst for olefin
polymers.
