abstract = {We have performed in situ X-ray diffraction measurements
of cubic silicon carbide (SiC) with a zinc-blende crystal
structure (B3) at high pressures and temperatures using
multi-anvil apparatus. The ambient volume inferred from the
compression curves is smaller than that of the starting
material. Using the 3$^{rd}$-order Birch-Murnaghan equation
of state and the Mie-Grüneisen-Debye model, we have
determined the thermoelastic parameters of the B3-SiC to be
K$_0$=228±3 GPa, K$_0$’,=4.4±0.4, q=0.27±0.37, where
K$_0$, K$_0$’ and q are the isothermal bulk modulus, its
pressure derivative and logarithmic volume dependence of the
Grüneisen parameter, respectively. Using the 3rd-order
Birch-Murnaghan EOS with the thermal expansion coefficient,
the thermoelastic parameters have been found as
K$_0$=221±3 GPa, K$_0$’,=5.2±0.4,
α$_0$=0.90±0.02 ⋅ 10$^{−5}$ ⋅ K$^{−1}$,
where α$_0$ is the thermal expansion coefficient at room
pressure and temperature. We have determined that paired
B3-SiC – MgO calibrants can be used to estimate pressure
and temperature simultaneously in ultrahigh-pressure
experiments up to 60 GPa.},
