碩士 === 國立成功大學 === 地球科學系碩博士班 === 90 === Hexagonal form of SiC, moissanite, is a strong material with superb heat conductivity that is suitable for serving as anvils in the gem anvil cells. The moissanite anvil cell (MAC) has the capability of generating pressure up to 50 GPa and temperature up to 1500℃, separately. It is feasible that simultaneous high pressure and temperature can be obtained at 10 GPa at maximum temperature of 1500℃ in the MAC. In this experiment, the frequency shifts of diamond Raman mode with temperature and pressure has been conducted in the MAC up to 1200K and 10 GPa, respectively. Potential applications of MAC to the investigation of the Earth's transition zone are currently undergoing.
