Abstract :
Crystal morphology, crystal structure and atomic coordinates of tricalcium silicate (C3S, 3CaO · SiO2) which is the main components of cement clinker were studied. Through Xray powder diffraction analysis and associated calculation, we gained the C3S precision cell parameters and atomic coordinates, then built three-dimensional models of C3S crystal structure. A C3S crystal electron backscatter scattering diffraction (EBSD) precise crystallographic database is established by EBSD test, [1] and it lays the foundation of study C3S from orientation angles [2-3], we standardized electron backscatter diffraction pattern (EBSP) of C3S crystal and took its EBSD phase identification test too by the database and its conclusions tally with that of X-ray powder diffraction test and calculation quite well.
