ABSTRACT:
A method for making metastable compounds of Me metal, argon and hydrogen, comprising the steps of generating a high frequency plasma discharge in a flow of hydrogen-argon gas mixture, the plasma discharge having a higher temperature plasma generating active region and producing a flow of plasma downstream of the plasma discharge; establishing a zone of substantially zero axial flow of the mixture within the active region of the plasma discharge relative to the flow of plasma immediately downstream of the generating means; introducing finely powdered Me metal into or near the zone and within the active region at a rate conducive to evaporation of the metal in the plasma discharge; rapidly cooling the reaction products resulting from interaction of the Me metal with the plasma to precipitate a solid component; and passivating the surface of the solid component.
