Crystal Structure of Tellurium at High Pressures

Abstract
Powder x‐ray‐diffraction studies on tellurium up to 150 kbar show only two structural transitions at 40 and 70 kbar in agreement with Bridgman's work. The structure of the 40–70‐kbar phase is unsolved. Above 70 kbar, it is proposed that tellurium is isomorphous with β‐polonium and is rhombohedral with a=3.002±15 Å, α=103.3°±3° (P=115 kbar), space group R3̄m with an atom in 1a (0, 0, 0).
