Its crystal structure has been determined by X-ray diffraction method(2,3)Its space group is P(21/b),Z=2, with an ideal chemical formula of Fe23+Fe2+(SiO4)2. The value of ratio Fe3+/Fe2+ of samples is in the range from 1.5 to 1.8. Its Mssbauer spectra at room temperature has been successively reported[1,4].展开更多
