Abstract:
Tungsten nanopowders were synthesized by a chemical metallurgy method at 440–640°C from WO3 precursors possessing different specific surfaces. The α-W nanopowder synthesized at 640°C was not pyrophoric, while the α-W containing the traces of oxides obtained at 480°C was pyrophoric. The temperature interval for the α-W synthesis was revealed as very narrow, from 470 to 490°C.
