Abstract
Processes are provided for preparation of precursors of Group III-V compounds, i.e., nitrides, phosphides, arsenides, antimonides and bismuthides of boron, aluminum, gallium and indium. The precursors are easily converted, e.g., by thermal decomposition, to the Group III-V compounds which are useful as thin-film coatings for aerospace components or as powders which may be shaped as desired.
