Abstract: A method for synthesizing a TiB2 powder includes the reduction of titanium oxide by carbon in the presence of a source of boron, the method includes heating a mixture of a carbon source, a boron carbide powder whose median particle diameter is between 5 and 100 microns and a powder of titanium oxide whose median particle diameter is between 5 and 80 microns, the mixture being placed in an enclosure under an inert gas sweep flow rate between 0.5 and 10 L/min/m/m3 of enclosure at a temperature of between 1500° C. and 2000° C., as well as the TiB2 powder obtained by such a method.
