In this paper, we introduce static black hole with accounting of f (R) gravity. First, we study thermal
properties and phase transition of corresponding black hole. Also, here we do correction to the entropy
and temperature at same time in above mentioned black hole. Second step, we obtain such corrected
thermodynamical properties and study the P − V critically and phase transition. We also investigate
the effect of correction term on the critical point and stability of the system. Finally, we compare the
obtained results from corrected and uncorrected of thermodynamical quantities.
