Raman spectra of synthetic HfSiO 4 were determined to pressures of 38.2 GPa. Changes in the spectra indicate that HfSiO 4 undergoes a room-temperature phase transition from the hafnon structure (I4 1 /amd space group) to the scheelite structure (I4 1 /a space group) at a pressure of ~19.6 GPa. Upon
An in situ Raman spectroscopic study was conducted to investigate the pressure-induced phase transformation in the synthetic ZnCr 2 O 4 spinel up to pressures of 70 GPa at room temperature. Results indicate that ZnCr 2 O 4 spinel starts to transform to the CaFe 2 O 4 (or CaTi 2 O 4 ) structure at 17
