Large-diameter rare earth barium copper oxide superconducting target material and preparation method thereof
The invention discloses a preparation method of a large-diameter rare earth barium copper oxide superconducting target material. The large-diameter rare earth barium copper oxide superconducting target material is prepared by: step 1, uniformly mixing initial raw materials according to a certain proportion without adding any binder to obtain mixed powder; and step 2, placing the obtained mixed powder in a high-temperature alloy steel mold, and carrying out non-vacuum pressure sintering to obtain the large-diameter rare earth barium copper oxide superconducting target material. In addition, theinvention further discloses a large-diameter rare earth barium copper oxide superconducting target material which is prepared by adopting the preparation method. In addition, the invention also discloses a superconducting film which is prepared from the large-diameter rare earth barium copper oxide superconducting target material. According to the large-diameter rare earth barium copper oxide superconducting target material, the yield of the large-diameter superconducting target material can be remarkably improved, the occurrence probability of macroscopic or microcracks of the target material is reduced, the density of the target material is improved, and harmful impurity elements in the target material can be reduced.
