Thermal expansion of rock salt and wurtize phases of Zinc Oxide nanomaterials has been studied using various relationships between volume thermal expansivity and temperature. The numerical values of volume thermal expansion coefficient for rs-ZnO and w-ZnOnanomaterials have been calculated in low and high temperature ranges. It is observed that in low temperature range i.e. upto room temperature, volume thermal expansion coefficient increases with slow rate with temperature for both the phases of Zinc Oxide while in high temperature range, thermal expansion coefficient increases with high rate with increase in temperature in the case of rs-ZnO and with slow rate in the case of w-ZnO. The available experimental and theoretical research support these theoretical predictions that demonstrates the validity of the work.
