Lattice Dynamics and High Pressure Phase Stability of Zircon Structured Natural Silicates

Preyoshi P. Bose, R. Mittal, S. L. Chaplot

We report a lattice dynamics study of relative stability of various phases of natural silicates MSiO4 (M=Zr, Hf, Th, U) as a function of pressure (P) and temperature (T), which is…
