Abstract

PURPOSE:To stabilize the good superconductive characteristic for a long time by preliminarily baking the powder of a specific oxide or carbonate, crushing it, mixing the baked body powder thus obtained and an organic vehicle, and using the paste thus obtained. CONSTITUTION:Powders with the average grain size of 5mum or less of the oxide or carbonate of elements A-C selected among elements of groups IIa, IIIa in the periodic table, elements of groups IIa, IIIa in the periodic table, elements of groups Ib-IIIb, VIIIa in the periodic table respectively are mixed at the atomic ratio satisfying the equation I to obtain the raw material powder. This raw material powder is preliminarily baked, the baked body thus obtained is crushed to the average grain size of 10mum or less, the baked body powder is mixed with an organic vehicle into paste, which is coated on a substrate by the screen printing method and dried and formally baked, and a thick film made of a perovskite or pseudo perovskite composite oxide superconductive material having the composition expressed by the formula II and the average crystal grain size of 15mum or less is formed on the substrate. In the equation, 0<w-y<=1, D is oxygen, and 1<=z<=5. The good superconductive characteristic can be thereby obtained for a long time.
