Abstract

The tolerance factor of ABO3-type ilmenite by analyzing the ABO3 ilmenite crystal structure is established, and combining with the electro negativity difference, regularities governing the formation 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 (Zn1-x, Mx)TiO3 (M denote Mg, Ni, Co). According to the results of statistical analyzing the tolerance factor and electro negativity difference of the present ABO3-type ilmenite, the experience tolerance factor value and experience electro negativity difference value to form stable ilmenite compound are obtained, that is, t>0.80 and e>1.465.
