Nano-tungsten powder was prepared on the basis of an industrialized production technique, using WO2.72 as the raw materials. The phase, composition, morphology, thermal stability, special surface area and pore structure of the samples were characterized by XRD, EDS, SEM, FESEM, DTA-TG, BET and Pore Size Analyzer. The results show that high-quality nano-tungsten powder can be produced by reducing the hydrogen reduction temperature, slowing down the pushing boat speed, reducing the boat charging capacity and increasing hydrogen flow rate.
