normally gas/metal ratios for heavy metals (Fe, ni, Cu, etc) are in the
range 0.5–4.0 m3
kg–1 at normal temperature and pressure. The lower end
of this range, used in large, multi-ton atomisers for HSS production, gives
coarse powders with median sizes of 150–250 mm. The upper end of this
range, used in smaller units for special alloys, and with close-coupled nozzles,
might allow particle sizes of as fne as 30–40 mm for steels.
