[SIT21-P07] Internally resistive heated diamond anvil cell experiments with metal encapsulated minerals
Keywords:Internally resistive heated diamond anvil cell, high pressure-temperature experiments
In this study, we modified the internally resistive heated DAC technique for nonmetallic material. We developed a microfabrication technique for total metal encapsulation of the nonmetallic sample. The sample encapsulated by platinum was loaded in DAC with thermal insulator and connected with two electrical leads to make electrical circuit for resistive heating. We confirmed very stable and homogeneous heating for insulating sample at 30 GPa to 2450 K in the modified internally resistive heated DAC. The highest temperature which this method can generate depends on the metal heater encapsulating the sample. This method offers a larger heating volume with more stable and uniform temperature than laser heating and at temperatures much greater than those that can be generated by external resistive heating methods.
