“…1,2 The main objects of study have been phosphates, 3,4 vanadates, 5,6 tungstates, 7,8 molybdates, 9,10 chromates, 11,12 niobates, 13,14 and tantalates. 15,16 On the other hand, a group of compounds that have been barely studied under HP are orthoantimonates, among which only BiSbO 4 has been studied. 17 Contrary to the rest of the MTO 4 compounds, this material shows a surprising structural stability under HP, not undergoing any phase transition up to 70 GPa, the maximum pressure reached by studies.…”
