  Peculiar features exist in the stress-temperature phase stability diagram of
V$_{2}$O$_{3}$ such as a first order phase transition between the paramagnetic
insulating and metallic phases that ends with a critical point, quantum phase
transition, and a triple point. These features remain largely unexplored and
the exact nature of the phase transitions is not clear due to very limited
control over the stress in bulk or film samples. Here, we show the synthesis of
single-crystal V$_{2}$O$_{3}$ nanoplates for the first time using chemical
vapor deposition via van der Waals epitaxy. Thickness of the V$_{2}$O$_{3}$
nanoplates range from a few to hundreds of nanometres and they can be
mechanically exfoliated from the growth substrate. Using Raman spectroscopy on
the nanoplates, we reveal that upon heating, V$_{2}$O$_{3}$ enters
supercritical state for both tensiley strained and relaxed crystals with
similar out-of-plane response. Transmission electron microscopy on V2O3
nanoplates hints the existence of a structural change when the crystals are
heated. Our results show that V$_{2}$O$_{3}$ nanoplates should be useful for
studying the physics of supercritical state and the phase stability of
V$_{2}$O$_{3}$ to enable new horizons in applications.
