PURPOSE:To obtain a novel compound useful as a cationic conductor, an ion exchanger or a heat resistant heat insulator by providing a macro tunnel structure to a chain of coordination bodies in which Ti<4+> has the octahedral coordination of TiO6, M<3+> has the octahedral coordination of MO6 and Ga<3+> has the tetrahedral coordination of GaO4. CONSTITUTION:One or more kinds of alkali metallic oxides selected among K2O, Rb2O and Cs2O are mixed with titanium oxide, gallium oxide and one or more kinds of tervalent metallic compounds selected among aluminum oxide, iron oxide and chromium oxide in a ratio giving a composition represented by the formula (where A is one or more kinds of alkali metals selected among K, Rb and Cs, M is one or more kinds of tervalent metals selected among Al, Fe and Cr, X=0.1-2 and Y=0.1-10). The mixture is burned at >=1,000 deg.C to produce a novel tetragonal compound represented by the formula and having a tunnel structure.
