  • Publication number: 20210037812
    Abstract: A DSC (Differential Scanning calorimetry) electrode system capable of applying an electric field includes a differential scanning calorimeter, a computer, a signal generator, a self-pressurization liquid nitrogen tank and a reference crucible, wherein the self-pressurization liquid nitrogen tank is connected to the differential scanning calorimeter and used for controlling temperature in real time; the differential scanning calorimeter is connected to the computer and used for transmitting signals and recording experiment results. The DSC electrode system also includes a microelectrode crucible that includes a ceramic crucible, a ceramic crucible cover, welding spots, two electrodes and electrode wires, wherein the two electrodes are respectively fixed in the ceramic crucible; a gap is reserved between the electrodes and used for storing a tested sample; the welding spots are reserved at upper ends of the electrodes.
