ABSTRACT:
A process for production of ZrB.sub.2 powder in a molten salt bath by reaction of ZrCl.sub.4 or ZrCl.sub.2 with a boron halide and Al or Mg. In a preferred embodiment the salt bath comprises ZrCl.sub.4, KCl and NaCl maintained at a temperature of about 540.degree. to 660.degree. C. and solid Al powder is reacted with ZrCl.sub.4 and BCl.sub.3. The ZrB.sub.2 powder produced in a particularly preferred embodiment has a median particle size of about 1.1 microns, is equiaxed, and has only a single phase.
