发明名称 SUPERCONDUCTIVE MEMBER
摘要 PURPOSE:To make it possible to use a superconductive material having high superconductive critical temperatures in high stability and an optional shape by forming the captioned member with a supporting body buried in which a matrix in a two-dimensional or three-dimensional state is formed on a sintered superconductive material. CONSTITUTION:A mixed powder, in which powders of BaCO3, Y2O3, and CuO are made to have the ratio of Y:Ba:Cu as 1:2:3 in composition after baking, is ground and mixed in an emulsion body, and its particle diameter is made to below 10mum. A raw powder obtained is press molded then baked, and a baked body solidified is again ground to become 2-3mum with the emulsion body. The powder baked body obtained is mixed with a melt in which ethyl cellulose is melted with terpineol, and a new melt is coarsely mixed in the emulsion body. Furthermore, the new melt is made to a homogeneouslly mixed paste using a three-roll, and is filled in a 300mmX300mm tray. On the other hand, a mesh plate having a size of about 300mmX300mm made of stainless is prepared as a supporting body 1, the mesh plate is soaked in the tray and took out, and thereby a sintered body 2 as a superconductive member is obtained with a compact in which the mesh plate is buried sintered.
