Abstract
Equation of State for the Compression of Nanocrystalline Anatase TiO2
Author(s): Brijesh K. PandeyThe compression behavior of Nanocrystalline Anatase TiO2 has been studied to test the validity of fundamental equation of state. To validate our results five fundamental equation of states (viz. Murnaghan EOS, Birch EOS, Usual-Tait EOS, Kholiya EOS and Vinet EOS) are used to compute the pressure upto the compression ratio of 0.9478. In the present work it is observed that the result obtained by using Murnaghan, Usual Tait and Vinet equation of state are consistently very close and in good agreement with the experimental results. The results obtained by using Murnaghan and Usual-Tait equation of sate are very close to the experimental values than Kholiya and Vinet equation of state while the Birch equation of state has no agreement with the compression behavior of Nanocrystalline Anatase TiO2. With the validity of Murnaghan and Usual-Tait equation of sate for TiO2 the variation of isothermal bulk modulus of the sample has also studied and found its linear variation with pressure.
