Introduction of Research
The most abundant mineral in the earth is considered to be the perovskite structured mineral "bridgmanite", which controls dynamics in the earth's interior. Bridgmanite is stable above 25 GPa and 1000 ℃, which are extremely high pressure and high temperature conditions. Thus we forecast chemical and/or physical behavior of bridgmanite by investigating analogous minerals, such as CaTiO3 perovskite, and then directly challenge to research bridgmanite and other silicate perovskites by mainly using high pressure apparatus and quantum beam diffraction technique.
