Abstract
We investigated the clinker formation process using the high-temperature X-ray diffraction of a combination of high-speed semiconductor and the high-temperature heat attachment. As a result, the formation state of the high temperature phase of the clinker minerals which have hitherto only been identified in a single phase, we were able to observe in-situ by heating the cement raw materials. Reaction of the formation and disappearance of each clinker minerals in high temperatures, were consistent with previous findings. Formation temperature of the high-temperature phase of each clinker minerals were similar to previous findings. Effect of coexistence clinker mineral and clinker material composition for the phase transition temperature of high-temperature phase is small.
