High pressure compression behaviour of bulk and nanocrystalline SnO2

The present paper reports a simple theoretical study of the pressure dependence of compressibility of bulk and the nano crystalline SnO2 of three different sizes (3, 8 & 14 nm) by using Equation of state model. The present work demonstrates the effect of size and pressure on compression and shows that the compressibility of nano-crystals depends upon size. The comparison of present results with available experimental data proves the validity of present model at bulk as well as nano scale. It is also found in this study that compressibility increases with decreasing particle size which is consistent with other available experimental and theoretical data
