Abstract
An aluminum flux method of preparing binary, ternary, and quaternary single crystal metal hexaborides. The single crystals are prepared by mixing a metal oxide, carbonate, or nitrate compound with boron powder in an amount of aluminum which will solubilize the boron at a reaction temperature of from about 1200.degree. C. to about 1600.degree. C. The mixture is held at the reaction temperature for a sufficient time to form the desired single crystal hexaboride.
