Angle dispersive X‐ray diffraction experiments have been performed in a diamond anvil cell using different pressure media and a large volume cell (Paris‐Edinburgh cell) in order to determine the effect of pressure–temperature conditions on the high‐pressure phase of the binary compound gallium antimonide GaSb. In particular, fine analysis of the diffraction patterns obtained at high pressure and/or temperature have clearly evidenced the importance of the pressure medium and of micro‐strains which considerably modified the structure at high pressure.
