| titleOfInvention | Superconducting material |
| abstract | PURPOSE:To obtain a superconducting material of extremely great critical current density, by calendering superconductor powder produced from specific compounds or a mixture of said powder and a binder followed by sintering. CONSTITUTION:First, Dy(NO3)3.6H2O, Ba(CH3COO)2 and Cu(CH3COO).H2O are incorporated into pure water so that the ratio Dy:Ba:Cu is 1:2:3 followed by through mixing. From the resultant mixture, water is removed by dry spray process to effect drying along with combustion into powder. This powder is heated and calcined in an oxygen-contg. atmosphere at ca. 900 deg.C and then annealed at a rate of 20-50 deg.C/hr. The resulting powder is ground in trichloromonofluoroethane to make superconductor fine powder. This fine powder is either directly or in the form of a mixture with liquid paraffin as the binder and zinc stearate as the lubricant, calendered followed by heating and sintering in a vacuum at ca. 850 deg.C for ca. 5hrs. and then annealing a 520 deg.C, thus obtaining the objective superconducting material. |
