A technique has been developed for heating high-pressure metal samples to very high temperatures by means of electrical resistive heating of thin-film heating elements in a diamond anvil cell. Key features of this design include the use of chemical vapor deposited (CVD) layers of diamond for electrical insulation, and thin-film lithographic patterning for fabrication of the heating elements. Data will be presented from a heating experiment on gold to 20 GPa and T=2000K.
