Modifications of various parts of the high-temperature diamond-anvil cell improved the mechanical stability and the overall performance of the cell. Resistive-wire heating of the cell in 10−4–10−5 torr vacuum substantially increased its heating efficiency such that sample temperatures of up to ∼ 1000 °C can be reached at a low input power (about 120 W). With synchrotron radiation, high-quality, energy dispersive X-ray diffraction spectra were obtained from samples in the improved cell at intervals of 2–5 min and temperatures up to ∼ 1000°C. High-temperature spectra for two γ-(Mg,Fe)2Si4 spinels demonstrate the potential applications of using the improved cell for studying the geophysically important mineral phases under in situ high pressure temperature conditions.
