The exploration of QCD phase diagram at moderate temperature and wide range of baryon densities have influenced many people working in this area of research as it has many effective application in nuclear physics and astrophysics. It is assumed that hadrons are actual ground state of strong interaction in conventional models. Witten statement give the idea that the strange quark matter (SQM) could be actual ground state relatively to normal nuclear matter [1]. Later on Farhi and Jaffe demonstrated that SQM is absolutely stable near the normal nuclear saturation density within large range of parameters [2]. Also dense quark matter has drawn a lots of interest due to recent progress in phenomenon color superconductivity. The ultrarelativistic heavy ion collision experiments in RHIC and LHC may lead to the formation of quark matter. Theoretical models based on the quark degrees of freedom, such as quark meson coupling model, MIT bag model, chiral quark mean field model, NJL model and extended PNJL model can be used to study properties of quark matter. In present study, we use chiral SU (3) quark mean field model at finite temperature and density to study equation of state of asymmetric strange quark matter relevant for heavy ion collision experiments.
