一种REBCO高温超导块体材料的制备方法
摘要：
本发明涉及一种REBCO高温超导块体材料的制备方法，特别涉及REBCO高温超导块体材料的熔融织构生长方法。REBCO高温超导块体材料的熔融织构生长方法，包括灼烧工序；灼烧包括以下步骤：在所述前躯体的顶部加入籽晶；置于生长炉中，升温至最高温度，并保温；所述籽晶是具有缓冲层的沉积于单晶氧化镁上的NdBCO薄膜，所述最高温度是1095℃-1115℃。本发明解决了现在的REBCO高温超导块体材料的熔融织构生长方法的最高温度不高的问题。
摘要（英）：

The invention relates to a preparation method of Russian export blend crude oil (REBCO) high-temperature superconducting block materials, in particular to a melt texture growth method of the REBCO high-temperature superconducting block materials. The melt texture growth method of the REBCO high-temperature superconducting block materials comprises a firing work procedure, wherein the firing work procedure comprises the following steps of: adding seed crystals on the top of a precursor; and placing the seed crystals into a growth furnace, raising the temperature to the highest temperature and carrying out heat insulation. The seed crystals are NdBCO films which are provided with buffer layers and are deposited on single crystal magnesium oxide, and the highest temperature is 1,095 DEG C to 1,115 DEG C. The melt texture growth method solves the problem that the highest temperature of the existing melt tissue growth method of the REBCO high-temperature superconducting block materials is not high.
