abstract = {Based on synchrotron X-ray diffraction on phase-pure
samples, we revised the bulk moduli of the rhenium borides
Re$_7$B$_3$ (B$_0$(Re$_7$B$_3$) = 391(5) GPa) and
orthorhombic Re$_3$B (B$_0$ (orthorhombic
Re$_3$B) = 393(4) GPa) and determined the bulk modulus
of monoclinic Re$_3$B (B$_0$ (monoclinic
Re$_3$B) = 390(3) GPa). These results agree well with
the DFT calculations on the elastic properties.
Microcalorimetry was employed to obtain thermodynamic data
for Re$_7$B$_3$ and orthorhombic Re$_3$B and we determined C
$_P$ , $_298$ (Re$_7$B$_3$) = 210(4) J/mol, $\Delta
H^0_{298}$ (Re$_7$B$_3$) = 40558(400) J/mol,
$S^{0}_{298}$(Re$_7$B$_3$) = 267(2) J/mol K and
$\Theta_{D,298}$ (Re$_7$B$_3$) = 320(2) K, as well as
$C_{p,298}$(Re$_3$B) = 86(1) J/mol, $\Delta
H^0_{298}$(Re$_3$B) = 16950(170) J/mol,
$\Theta_{D,298}$(Re$_3$B) = 112(1) J/mol K and
(Re$_3$B) = 329(3) K. Hardness measurements were
performed for Re$_7$B$_3$, which gave a Vickers hardness
$H_V$(5 kgf) = 14.5(4) GPa and $H_V$(10
kgf) = 14.1(3) GPa. Electron energy loss spectroscopy
(EELS) was performed on orthorhombic Re$_3$B and ReB$_2$,
and the experimental spectra are well reproduced by theory
in terms of their absorption edges.},
