Abstract Polycrystalline BAs$_{x}$ ($x = 0.80$–1.10) compounds with different boron-to-arsenic elemental molar ratios were synthesized by a high-pressure and high-temperature sintering method. Compared with other ambient-pressure synthesis methods, high pressure can significantly promote the reaction speed as well as the reaction yield. As the content of arsenic increases from $x = 0.91$ to 1.10, the thermal conductivity of BAs$_{x}$ gradually increases from 53 to 65 W$\cdot$m$^{-1}\cdot$K$^{-1}$. Furthermore, the temperature dependence of thermal conductivities of these samples reveals an Umklapp scattering due to the increasing phonon population. This work provides a highly efficient method for polycrystalline BAs synthesis.
