摘要:

本文对超高纯氟化钇(YF3)的制备工艺开展了系统性研究,重点探讨原料预处理工艺并筛选最佳氟化剂。 通过改变Y2O3的球磨时间、转速及烧结温度等参数,结合X射线衍射(XRD)、热重分析(TGA)、粒度测试及Zeta电位等表征手段,确定了最优的预处理工艺条件。 将预处理后的Y2O3粉末分别与3种氟化剂(NH4HF2、HF气体及KF)进行氟化反应,通过XRD、X射线光电子能谱分析仪(XPS)、TGA、粒度、Zeta电位、扫描电子显微镜(SEM)、电感耦合等离子体-质谱(ICP-MS)及氧含量测定等多种表征手段系统对比了不同氟化剂制备的YF3性能。 结果表明,以HF气体为氟化剂时制备的YF3综合性能最优,其晶体结构完整,氟化程度充分。 Fe和Nd杂质质量分数分别为0.0021%和0.0002%,Cr质量分数为4.58×10-6%,氧质量分数仅为0.0052%,且颗粒分散性良好,无明显团聚现象。 本研究在实现原料节约、成本降低的同时,成功制备出可应用于高端技术领域中的超高纯YF3,为超高纯YF3的制备提供了研究思路。

Abstract:

This paper conducts a systematic study on the preparation process of ultra-high-purity yttrium fluoride (YF3), with a focus on the pretreatment of raw materials and the screening of the optimal fluorinating agent. By altering parameters such as the ball milling time, rotational speed, and sintering temperature of Y2O3, and combining characterization methods including X-ray diffraction (XRD), thermogravimetric analysis (TGA), particle size testing, and Zeta potential measurement, the optimal pretreatment conditions were determined. The pretreated Y2O3 powder was subjected to fluorination with three fluorinating agents, namely NH4HF2, HF gas and KF. The properties of YF3 prepared using different fluorinating agents were systematically compared via various characterization methods, including XRD, X-ray photoelectron spectroscopy (XPS), TGA, particle size analysis, Zeta potential measurement, scanning electron microscopy (SEM), inductively coupled plasma-mass spectrometry (ICP-MS), and oxygen content determination. The results show that the YF3 prepared using HF gas as the fluorinating agent exhibits the optimal comprehensive performance, with a complete crystal structure and adequate fluorination degree. The mass fractions of Fe, Nd and Cr impurities are 0.0021%, 0.0002%, and 6.65×10-6%, respectively, while the mass fraction of oxygen is only 0.0052%. Moreover, the particles are well-dispersed with no obvious agglomeration. This research not only achieves raw material conservation and cost reduction but also successfully prepares ultra-high-purity yttrium fluoride applicable to high-end technical fields, providing a research gramework for the preparation of ultra-high-purity YF3.
