The purpose of this paper is to study the elastic behaviour of different kinds of Alkali Halides such as KF, KCl, KBr, KI at different temperature upto their melting point and temperature-dependent ultrasonic velocities and ultrasonic Grüneisen parameter have studied in Potassium Halide crystal. We have also computed second, third and higher order elastic constant using Coulomb and Börn-Mayer potential with the help of general potential i.e. nearest neighbour distance and hardness parameter. Further parameter like Bulk Modulus, Young’s Modulus, Shear Modulus etc have also been find out for the future achievement. The theory is tested for SOECs, TOECs, FOECs and correlated physical properties of potassium halide at different temperature. The study of higher order elastic constant of potassium halide crystals have been undertaken for aim of giving needed and prime information. The data of higher order elastic constants and some physical properties are in suitable concurrence with other theoretical and experimental data.
