Ultrahigh pressure and high temperature experiments using a laser heated diamond anvil cell in multimegabar pressures region

Abstract

Achieving the extreme pressure and temperature conditions found in the Earth's inner core has been one of the major experimental challenges. In this article, recent development of ultrahigh-pressure and high-temperature techniques in multimegabar pressures region using a laser heated diamond anvil cell is described. Results from recent experiments about phase relations of silica and iron up to 300 GPa and 2000 K are reviewed.
