METHOD OF MAKING ARTICLES OF COMPLEX FORM FROM HIGH-TEMPERATURE SUPERCONDUCTIVE CERAMICS Russian patent published in 1995 - IPC

Abstract RU 2044716 C1

FIELD: instrument making. SUBSTANCE: ceramic powder is heated at 120-140 C for 2-4 h and cooled up to 80-90 C. Then surface-active substance is added at concentration 0.3-1 wt.-% and binding and casting slip is carried out at 90-95 C under pressure 5-6 atm. Binder is calcined out at 100-110 C. Positive effect: Tc= 90-92K 90-92 K, ΔTc=2K 2 K, Jk= 50-150 A/cm3. Material is used for making devices using superconductivity. EFFECT: enhanced quality of material.
