High-Temperature, high-pressure X-ray investigation of dicalcium silicate

摘要

Energy-dispersive X-ray powder diffraction experiments have been investigated at high temperature and room pres- sure, and at high pressure and room temperature, starting from either γ- or β-Ca_2SiO_4. High-temperature studies were performed up to 1980 K, using a versatile heating cell. The high-temperature phase transformations previously Described were reexamined.
