During normal pressure sinterring, addition of the obstruction medicine to in the ceramic membrane in order to obstruct the grain growth of the particle

摘要

The compound electron which is chosen from the ceramic oxide which form of the crystal lattice which possesses the oxide ion hole in use temperature, further in details, cubical phase, fluorite phase, perovskite phase, is brown needle nickel ore phase or pairokuroa phase of oribiriusutaipu form, is doped/oxygen O^2- anionic conductivity chemical compound (C₁) at least 75vol%, and The ceramics of oxide type and the ceramics of non oxide type, the metal, it is chosen the metal alloy or these types from the blend of the substance, chemical compound (C₁) with the chemical compound which differs (C₂) 0.01 - 25vol%, and formula: The chemical compound which is formed at least from the chemical reaction of 1 where xF _{c1+yF c2zF c3} (in formula, F _c1, F _c2 and F _c3, chemical compound C₁, C₂ and display C₃ respective empirical formulas, x, as for y and z, are displayed numerical value of ratio of 0 or more is displayed) by (compound ones which include C₃) 0vol% - 2.5vol% (M). This invention, as compound conductivity compound ones of the catalyst membrane reactor where it is intended, that you use for synthesizing the synthetic gas production method, and the methane of compound ones or with the catalytic oxidation of the natural gas, and/or as compound conductivity compound ones for the ceramic membrane where it is intended that you use in order to separate oxygen from the air, regards also the use.
