Outline
The two-stage 1 000 tons Walker module large-volume high temperature and high pressure apparatus can generate different pressures with different truncated edge lengths of anvils (12, 8, 6, and 4 mm). If tungsten carbide is chosen as an anvil, the maximum pressure obtained is above 20 GPa. The sample assemblies of Walker module apparatus are determined. The pressure calibration is performed by the fixed points of phase transitions method for different truncated edge lengths. The phase transition pressures of standard materials of pressure calibration (Bi, Tl, ZnTe, Pb, ZnS, GaAs) are achieved by measuring the resistance change with oil load under high pressure. The calibration curve of the sample pressure versus load is obtained, which provides exact information for future high pressure experiments using this apparatus.
