Procedure

Accordingly, the present invention provides an improved process for the production of zirconium boride, which comprises mixing powders of zirconium chloride in the range of 20-25% wt, Boric acid (H3BO3) in the range of 35-44 wt % and small cut turnings Magnesium (Mg) in the range of 33-40 wt % and pelletising the mixture so prepared, igniting the prepared pellets under inert atmosphere and leaching the resultant product (ZrB2 and MgO) with leachant to obtain zirconium boride.
