Iron-selenium-tellurium superconducting target material and preparation method thereof
The invention belongs to the technical field of target material preparation, and relates to an iron selenium tellurium superconducting target material and a preparation method thereof. The iron selenium tellurium superconducting target material is FeySexTe1-x, wherein x is more than or equal to 0.4 and less than or equal to 1, and y is more than or equal to 0.6 and less than or equal to 2.0. The precursor FeySe1-xTex polycrystalline powder is subjected to high-temperature hot pressing sintering, and the FeSeTe superconducting target material which is good in uniformity, extremely high in density and free of cracks and pores is obtained. The preparation method can also meet different requirements, multiple FeSeTe target materials with different components can be prepared at the same time, and the preparation efficiency and flexibility of the FeSeTe target materials are greatly improved. Compared with the prior art, the preparation method has the advantages that the preparation time is shortened while the high quality of the FeSeTe target material is ensured, so that the preparation efficiency of the target material and the stability of the performance of the target material are improved.
本发明属于靶材制备技术领域，涉及一种铁硒碲超导靶材及其制备方法。所述的铁硒碲超导靶材为FeySexTe1‑x，其中0.4≤x≤1，0.6≤y≤2.0。通过将前驱体FeySe1‑xTex多晶粉末使用高温热压烧结的方式，得到均匀性好、致密度极高、无裂纹、无气孔的FeSeTe超导靶材。所述的制备方法也可以满足不同的需求，同时制备多个成分不同的FeSeTe靶材，大幅度提升FeSeTe靶材的制备效率以及灵活性。与现有技术相比，本发明在保证FeSeTe靶材高质量的同时，缩短制备时间，从而提高了靶材的制备效率以及靶材性能的稳定性。
