摘要

摘要提出了在合成具有低铁掺杂的高温超导体 Y1-xFexBa2Cu3Oy 的初始阶段使用溶胶-凝胶工艺的改进方案。比较了溶胶-凝胶法和固态合成法得到的样品的特性。结果表明，掺杂剂在整个溶胶-凝胶样品体积中的分布更加均匀，因此可以获得具有更好微观结构和性能特征的材料。

Synthesis of a High-Temperature Superconductor Y1–xFexBa2Cu3Oy by the Sol-Gel and Solid-State Methods

A modified version of the use of the sol-gel process at the initial stage of the synthesis of a high-temperature superconductor Y_1–xFe_xBa₂Cu₃O_y with low Fe doping is proposed. The properties of the samples obtained by sol-gel and solid-state synthesis are compared. It is shown that a more uniform distribution of the dopant throughout the volume of the sol-gel samples makes it possible to obtain materials with improved microstructural and performance characteristics.
