摘要

如何细化晶粒一直是制备高性能陶瓷靶材的难题。本研究提出了掺杂诱导晶粒细化策略，通过优化烧结时间和保温温度，获得了掺杂不同浓度 Pr 的氧化铟锌（Pr-掺杂 IZO，PrIZO）靶材。研究人员详细探讨了掺镨含量对 PrIZO 靶件致密化过程中的密度、相微观演化、晶粒尺寸和电阻率的影响，以及晶粒生长动力学和晶粒细化机制。结果表明，Pr:In:Zn=0.01-0.03:1:1 原子比的 PrIZO 靶件均表现出优异的性能，在 1350 ℃ 低烧结温度下具有高致密性（99.10%）和较小的平均晶粒尺寸（3.0 μm）。此外，XRD 和 EDS 分析表明，PrIZO 靶件由 In2O3 和 Zn3In2O6 组成，并含有少量 PrInO3，这是由 Pr 元素的有限固溶性形成的。结合理论计算推断，晶粒细化的机理是由于溶质转化和细小的 PrInO3 分布在 In2O3 相的晶界上，产生了晶界迁移的阻力效应，进而阻碍了晶粒的进一步生长。

Grain refinement for indium zinc oxide ceramic targets by praseodymium doped induced blocked boundary migration

How to refine the grain has been a difficult problem in the preparation of high-performance ceramic targets. In this work, the doping-induced grain refinement strategy was proposed, indium zinc oxide doped with different concentrations of Pr (Pr-doped IZO, PrIZO) targets were obtained by optimizing the sintering time and holding temperature. Effects of Pr doping content on the density, phase microevolution, grain size and resistivity during the densification process as well as the kinetics of the grain growth and the mechanism of grain refinement of PrIZO targets were investigated in detail. The results demonstrated that PrIZO targets with the atomic ratios of Pr:In:Zn = 0.01-0.03:1:1 all exhibited the excellent performance with high densification (>99.10 %) and mere average grain size (<3.0 μm) at low sintering temperature of 1350 °C. Additionally, XRD and EDS analysis indicated that PrIZO targets were composed of In₂O₃ and Zn₃In₂O₆ with slight PrInO₃, which formed by the limited solid solubility of Pr element. Combined with theoretical calculations, it inferred that the mechanism of grain refinement was attributed to the solute transformation and fine PrInO₃ distributed at the grain boundaries of In₂O₃ phases, which produced the drag effect of grain boundary migration, then hindering the further growth of grains.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
