MgSiO3 perovskite and ferropericlase (Mg, Fe)O are generally considered as the most dominant components in the Earth's lower mantle. The experimental data of these phases at high pressures and high temperatures play a key role to constrain the composition of the Earth's lower mantle. However, high pressure experiments at lower mantle conditions, especially the shock wave experiments, are restricted since it is impossible to collect the high-phases of the samples in nature. We introduce the experimental methods to synthesize large bulk MgSiO3 perovskite and ferropericlase (Mg, Fe)O using piston-cylinder and mutli-anvil apparatuses, and the synthesized samples were analyzed by micro electronic probe, Raman spectrum, and X-Ray diffraction. This makes it possible to do shock wave experiments with the large bulk MgSiO3 perovskite and ferropericlase (Mg, Fe)O as starting materials.
