%X The p-V-T equation of state of superhard boron suboxide B<sub>6</sub>O has been measured up to 6 GPa and 2700 K using multianvil technique and synchrotron X-ray diffraction. To fit the experimental data, the theoretical p-V-T equation of state has been derived in approximation of the constant value of the Anderson-Grüneisen parameter δ<sub>T</sub>. Bulk modulus B<sub>0</sub> =181 GPa and its first pressure derivative B<sub>0</sub>′ = 6 at 300 K; two parameters describing thermal expansion at 0.1 MPa, i.e., a = 1.4 × 10<sup>−5</sup> K<sup>−1</sup> and b = 5 × 10<sup>−9</sup> K<sup>−2</sup> as well as δ<sub>T</sub> = 6 have been included in the model. The good agreement between fitted and experimental isobars has been achieved to the absolute volume changes up to 5
