This invention regards the group, and its production method compound ceramic oxide being new. This group of new compound ceramic oxide is something of general type, Mg2 MM'O6+x here, is the M= rare earth metal ion or yttrium or lanthanum, is M'= Sn, Sb, Zr, Hf, Ta, and Nb; Here, it is -0.5x+0.5, the said group has the pyrochlore structure which has defect. At the time of forming the necessary phase, constitution in either of the metal ions fluctuation can be allowed up to very small amount of 8%. As for production method of the new chemical compound group, (a) up to very small amount of 8% constitution in one metal ion it is allowed in formation of the phase whose fluctuation is necessary, the 2:1 which is necessary for the formation of the chemical compound of general type Mg2 MM'O6+x: Mg of mol ratio of 1: M: M'ga in order to be obtained, the chemical compound of magnesium, M and M' (here, it is either yttrium, lanthanum or the rare earth atoms and profit and M'= antimony, tin, is zirconium or tantalum) to mix M, (b) the chemical compound which is used with process (i) to be able select oxide and carbonate, from the chloride, alkoxide, nitrate and the sulfate etc, desirably, the salt which is used to be selected from oxide or carbonate, (the blend which is obtained with c) process (i) to be able be mixed ball mill processing namely damp medium, as for damp medium the water, alcoholAcetone or it is each other organic solvent and profit, if drying the ball mill processing slurry which is obtained, it removes the liquid, the dry powder profit, (d) at single process, or removes the reactant after the heating in several hours and it checks and concerning phase formation it is necessary, after the pulverizing it heats that for the second time, at the process which can add the intermediate pulverization up to maximum of 5 times, at the time when it differs the range of 3 hours or 50 hours according to need the blend which is obtained, 1000 or it heats to the temperature of the range of the 1600C, process is included.
