Summary

A high-temperature diamond-anvil press which allows X-ray diffraction investigation of polycrystalline materials at high pressures up to 30 GPa and at high temperatures up to 500°C is described. Several improvements in the heating efficiency, temperature uniformity, and alignment procedure have been made to the anvil press. Preferred orientation effects from the sample have been eliminated. This device has been used to study the Group Vb elements phosphorus, arsenic, and antimony at high pressure and temperature to determine the stability of the rhombohedral A7 structure with respect to the closely related primitive simple cubic structure.
