Efficient Synthesis of WB-WB Powders with Selectivity for WB Content.

We proposed an efficient method toward the synthesis of higher tungsten boride WB in the vacuumless direct current atmospheric arc discharge plasma. The crystal structure of the synthesized samples of boron-rich tungsten boride was determined using computational techniques, showing a two-phase system. The ab initio calculations of the energies of various structures with similar X-ray diffraction (XRD) patterns allowed us to determine the composition of the formed higher tungsten boride.
