In the present book, a comprehensive study of the crystals using various thermodynamic relations and equation of states has been done.This is a research oriented book helpful for the students of Crystallography and Material Study and for scientists, engineers and students who are working with empirical equations of state and thermodynamic approximations.In this work, the proper analysis of high pressure, high temperature properties of different crystals is done that can be used to acknowledge the research in different regions.This book gives a brief preview of various equations of state that...
