摘要: The origin of silver doping effects on Y‐Ba‐Cu‐O superconducting ceramics, such as a high‐temperature shift the point at zero resistivity in measurements and an increase critical current density, was sought by transmission electron microscopy observations. Sintering strongly promoted together with suppression formation liquid phase grain boundaries silver. Consequently, phase, which is not superconductor, present almost all silver‐doped while this pure ceramics.
