Production of spherical tungsten-carbide granules

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    A study was made of the barrel-rotation process for the preparation of spherical particles, 150–700 μ in size, of refractory compounds.

  2. 2.

    It was shown that, for effective granulation by this technique, it is necessary to use a finely-divided powder with 50% of its particles 2–3 μ in size and a moisture content of not more than 0.3%,

  3. 3.

    The granule density was measured as a function of granulation time. The best consolidation of the granules was found to be attained after 3 h.
