Abstract
A method of producing intermetallic particles such as TiAl.sub.3, NiAl.sub.3 and others utilizes a chamber having a discharge immersed in molten media such as molten metal and having a plasma therein extending from the molten media at the chamber discharge to a site above the discharge. One or more constituents of the desired compound are provided to said site and converted into a superheated spray. The constituents react with each other or with one or more constituents in the aforesaid media to produce the desired compound. A gas exits the chamber and enhances contact and reaction and also transfer to the media.
