One of the biggest disadvantages in high- superconducting ceramics is the difficulty of forming into a desired shape. This paper shows a new route for fabrication of ceramic superconductors with complex shapes such as pipes, hollow coils, and honeyco

A new method for joining bismuth-based superconducting glass-ceramics has been developed; they are joined easily by melting-annealing with a liquid natural gas (LNG)-oxygen flame. Two edge portions of the glass-ceramics to be joined are melted by a h

Bi–Sr–Ca–Cu–O (BSCCO) superconducting whiskers (2212 phase) were prepared by heating in air the compacted specimens of the mixtures of melt-quenched Bi2SryCa2Cu4Al1Ox powders and alumina powders. Formation of the whiskers depends on the compo

As-cast Ag 2 O-doped Bi 2 Sr 2 Ca 1 Cu 2 O x material was converted into a superconducting ceramic by reheating in an evacuated and sealed silica-glass tube. The microstructure of the glass-ceramic obtained was characterized by electron microscopy. P

Ag2O-doped superconducting Bi2Sr2Ca1Cu2Ox ceramics were prepared by a melt-quenching–reheating method. It is found that the Ag2O-doped, as-cast specimens exhibit superconductivity (Tc= around 80 K) by heat treatment at temperatures around 800°C ev

Pipes or hollow cylinders in the Bi-Sr-Ca-Cu-O system were found to be fabricated easily by inspiring or sucking the low viscosity melt into a cold silica glass tube. The outer part of the cast rod-like melt solidified, and the inner hot low-viscosit

The conventional electric quench-detecting system of AC superconducting coil is vulnerable to the electromagnetic noise, so the systems have problems in quench-detecting sensitivity and reliability. Recently the systems combined with physically diffe

The critical current (Ic) of high‐Tc pipe‐like superconductor was found to increase under external magnetic field, when the superconductor pipe and bar are constructed into coaxial cylinder configuration. The superconductor specimens in the Bi‐
