| 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.
