Abstract

PURPOSE:To obtain a heat insulating material capable of providing easily and in large amt. molded bodies having high insulating effect and thermal shock resistance, and complex shape of high dimensional precision by molding a kneaded mixture consisting of superconductor powder and org. binder. CONSTITUTION:Fine powder obtd. by drying and calcining a mixture consisting of Dy(NO3)3.6H2O, Ba(CH3COO)3, Cu(CH3COO).H2O mixed in 1/2/3 proportion of Dy/Ba/Cu, is calcined in O2 atmosphere, and cooled slowly. Thus, superconductor powder (A) having about 1mu particle size is obtd. The powder (A) is then pressed and sintered in the air, then crushed to attain 15-100mu particle size distribution to obtain thus superconductor powder (B). After mixing (A) with (B) in, for example, 2/1 proportion, an org. binder (C) such as nylon 12 powder 12, etc., is mixed there with and dispersed. The mixture is kneaded in an extruding kneader at 220-260 deg.C. The product is cooled and cut to pellets. A heat insulating material is obtd. by molding the pellets.
