Conclusions

  1. 1.

    A study was made of the single-stage reduction of WO3 to W in an industrial GSPI muffle furnace with a direct-flow feed of hydrogen into the furnace muffle.

  2. 2.

    It is shown that, with hydrogen supplied by the direct-flow technique, it is possible to produce in a single stage, at unchanged furnace output, a homogeneous, fine-grained tungsten powder with an adsorption of more than 0.2 mg/g and a mean particle size of < 1μ.

  3. 3.

    An investigation was carried out of the effect of sintering temperature on the properties of T15K6 alloy produced from tungsten powder prepared by the direct hydrogen flow technique.

  4. 4.

    It is shown that, compared with a standard T15K6 alloy, an alloy of the same composition produced from tungsten powder prepared in a muffle furnace with a direct-flow hydrogen supply possesses a finer-grained WC phase structure and superior physicomechanical and cutting properties.
