摘要： The invention relates to a method for curing cracks in ceramic shaped bodies. According to the inventive method, a filling material which melts at a lower temperature than the material of the shaped body and/or which is flowable at a lower temperature than the material of the latter is applied at least in the area of a crack on the surface of the shaped body and/or is inserted in at least one crack. The shaped body with the applied and/or inserted filling material is subsequently heated up to a temperature at which the material of the shaped body does not yet melt or/and is not yet flowable, however, at which the filling material is at least partially melted on and is in a flowable state. In addition, the filling material is comprised or substantially comprised of non-metallic compounds and is partially crystallized out. The shaped body with the filling material is then cooled.

摘要： The invention relates to a method for producing a shaped body. According to the invention, a mixture of oxidic basic powders or a supraconductor material containing at least 30 % by volume flake-shaped primary particles, with a composition which is such that it forms a high-temperature supra-conductive material when later subjected to the appropriate thermal treatment, is reduced by means of milling, shearing and/or rolling, in such a way that the resulting reduced powder has a particle size distribution with a d90 value

摘要： The present invention relates to a high-temperature superconducting component in which a predetermined cross-sectional surface comprises a current-conducting section. This current-conducting section is brought into contact with a protection conductor so that the critical current that circulates when the superconductor reaches the normal line can be absorbed in a non-destructive manner and for at least 1 second by said protection conductor, and further sent forward. This invention also relates to a method for producing this component.

摘要： According to the inventive method for producing a superconductive coil, a shaped body consisting of a material which is superconductive or which becomes superconductive upon subsequent heat treatment is coated with reinforcement agents and is given the geometric shape of the future coil. The invention also relates to a superconductive coil produced according to this method. Said inventive superconductive coil has low alternating current loss and consists of a highly textured superconductive material and is oriented in such a way that the platelet levels are directed considerably in the direction of the course of the coil. The coil is formed from a superconductive solid part.

摘要： The invention relates to a method for coating shaped bodies made of a superconducting material based on (Y/SE)BaCuO. The invention is characterized in that a coating consisting of a coating material is applied to at least one part of a surface of the shaped body, whereby the coating material at least partially melts at a lower temperature than that of the material of the shaped body and/or is flowable at a lower temperature than that of said material. The shaped body with the applied coating material is heated to a temperature at which the material of the shaped body does not yet melt and/or is not yet flowable, however at which the coating material is at least partially melted thereon and/or is in a flowable state. In addition, at least one part of the area of the shaped body located near the surface is modified at said temperature and/or during a successive cooling, and the shaped body treated in such a manner is enriched with oxygen during cooling and/or during a successive heat treatment, whereby the modification contributes to the increase in remanent induction and/or to the critical current density of the shaped body enriched with oxygen. The invention also relates to a shaped body made of a superconducting material which is based on (Y/SE)BaCuO and which can be obtained by using the above-mentioned method. Said superconducting material contains at least one rare-earth element selected from the group of Y, La, Ce, Pr, Nd, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu and comprises a maximal value of remenant induction of at least 1100 mT at 77 K and 0 T.
