  The critical behavior of Myers-Perry black holes with equal angular momenta
in even dimensions are studied. We include the corrections beyond the
semiclassical approximation on Hawking temperature in the grand canonical
ensemble. Having done so, we find that the critical behavior and critical
exponents of Myers-Perry black holes correspond to those of a Van der Waals
liquid-gas where this analogy holds in any dimension. Also, using Ehrenfest's
equations, we calculate the order of the phase transition in the semiclassical
approximation for the canonical ensemble and beyond the semiclassical
approximation for the grand canonical ensemble near the critical point.
Finally, the Ruppeiner curvature formula is used to investigate the
thermodynamic geometry of Myers-Perry black holes.
