ABSTRACT:
A method of producing an aluminum boride (AlB.sub.2 or AlB.sub.12) in solid form comprises providing a body of molten aluminum containing suspended particles of an aluminum boride, and separating the particles e.g. by filtration from the bulk of the molten metal. Preferred filter media are alumina and carbon, each of which can be subsequently removed to leave the aluminum boride in solid form. The product is a useful precursor for production by reaction sintering of refractory composites containing titanium diboride.
