The reactions of boron carbide with titanium and zirconium carbides ha
ve been examined under various conditions. Reactive sintering of the i
nitial mixtures produces a heterophase material based on B4C-MeB2, via
a stage of lower boride formation. The reaction completeness is incre
ased by adding boron and boron silicide. The material has a finely div
ided structure and high hardness (42-45 GPa). Promising mixture compos
itions have been identified together with ways of optimizing the sinte
ring modes.
