This investigation will carry out controlled crystallization of superconductive phases of the Ba-A-Cu-O type (A = trivalent rare earth element) from a Ba-A-Cu-R-O molten mass where R is a glass network forming element such as B, Si, or P. This glass-ceramic route could be employed to obtain strong, uniform grain-sized superconductor with nearly zero porosity. Conventional glass- ceramic technology is used to obtain pressed and blown shapes, canes and wires.

这项研究将从BA-A-CU-O类型（A =三价稀土元素）的超导阶段进行受控的结晶，从BA-A-CU-R-O熔体弥补，其中R是玻璃网络形成诸如B的玻璃网络，Si或P。可以采用这种玻璃陶瓷途径来获得近乎零孔隙率的强，均匀的晶尺寸超导体。常规的玻璃陶瓷技术用于获得压制和吹动的形状，拐杖和电线。
