Popis: We performed the pressure calibration to 12 GPa for 14/6 type (octahedron edge length/WC truncated edge length, in mm) cell assembly in DS 6 × 1400 multi-anvil apparatus by using the phase transitions in Bi (I-II 2.55 GPa, III-V 7.67 GPa) and ZnTe (LPP-HPP I 9.6 GPa, HPP I-II 12.0 GPa). As verification and application, sound velocity measurements on polycrystalline Al2O3 to 12 GPa at room temperature were conducted and the ultrasonic result is in good agreement with previous reports. It demonstrates the feasibility of performing sound velocity measurements close to the mantle transition zone pressure condition in our laboratory.
