【Abstract】 The tolerance factor of ABO₃-type ilmenite by analyzing the ABO₃ ilmenite crystal struc- ture is established,and combining with the electronegativity difference,regularities governing the forma- tion and the stability of ilmenite-type compounds are discussed.The tolerance factor equation is proved appropriate for ilmenite structure by analyzing the structure stability of some ilmenite compounds,such as MgTiO₃,NiTiO₃,CoTiO₃,ZnTiO₃ and(Zn_1-x,M_x)TiO₃（M denote Mg,Ni,Co）.According to the results of statistical analyzing the tolerance factor and electronegativity difference of the present ABO₃-type ilmenite,the experience tolerance factor value and experience electronegativity difference value to form stable ilmenite compound are obtained,that is,t>0.80 and e>1.465.更多还原
