摘要
Analytical reagents have been used for preparation of pure C_3S and its solid solutions containing Fe_2O_3 or FeO. The data from M(?)ssbauer Spectra of samples suggest that 4Si^(4+) are replaced by 4Fe^(3+), 1Ca^(2+) by 1Fe^(3+), and 1Fe^(3+) occupies one octahedron hole; Fe^(2+) mainly replaced Ca^(2+). Spectroscopic Study has indicated there may be extream distortion and higher orientation disorder in (SiO_4) tetrahedron, the reduction of lattice order and translation symmetry by results of ionic replacements of Fe^(3+) or Fe^(2+) in C_3S crystal lattice.
