Abstract

Fine powders of refractory materials, e.g. stainless steel, chromium, molybdenum, tantalum, tungsten, thoria, alumina, magnesia, urania and tungsten, uranium, and sirconium carbides are formed, by heating the material in particulate form in an induction-coupled plasma in a gas stream and cooling the material while the particles are separated by the gas. As shown, argon flows through a connection 16 in a silica tube 1, and radio-frequency is supplied to a coil 2. The refractory material is fed through a funnel 14, melted or vaporized, and cooled, before being separated from the gas. <PICT:1033391/C6-C7/1>ALSO:Fine powders of refractory materials: thoria, alumina, magnesia, urania, and tungsten, uranium, and zirconium carbides are formed, by heating the material in particulate form, in an induction-coupled plasma in a gas stream, and cooling the material while the particles are separated by the gas. In the Figure (not shown), argon flows through a connection 16 in a silica tube 1, and radio-frequency is supplied to a coil 2. The refractory material is fed through a funnel 14, melted or vaporized, and cooled, before being separated from the gas.
