  • Method for coating a semiconductor material using high remanent induction, coated superconductor material and the use thereof
    Patent number: 6830839
    Abstract: 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.

  • Method for curing cracks in ceramic shaped bodies and shaped bodies treated in such a manner
    Patent number: 6638568
    Abstract: A method of curing cracks in a ceramic shaped body made from ceramic magnet materials or ceramic superconductor materials, in which a filling material which melts at a lower temperature than the material of the shaped body or is flowable at a lower temperature than the material of the shaped body is applied to the surface of the shaped body at least in the area of a crack and/or is introduced into at least one crack, in which the shaped body with the filling material is heated to and maintained at a temperature at which the material of the shaped body does not yet melt or is not yet flowable, but at which the filling material is in at least partially molten and flowable state at least until the fused filling material can penetrate at least partially into the crack, in which the filling material consists of non-metallic or essentially of non-metallic compounds and is at least partially crystallized, and in which the shaped body with the filling material is cooled, wherein the thermal crystallization conditions
