Abstract

High-crystalline α-alumina (Al₂O₃) nanoparticles were synthesized using a novel precipitation method and characterized through X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), Energy Dispersive Spectroscopy (EDS), and Selected Area Electron Diffraction (SAED). XRD confirmed the hexagonal corundum phase with lattice parameters a=b= 4.7624 Å, c= 13.002 Å. Crystallite size, strain, and energy density were estimated using multiple models, yielding a crystallite size of 56.92 nm. TEM showed spherical particles of 54.35 nm. EDS confirmed the purity, and SAED patterns confirmed high crystallinity. These nanoparticles are suitable for applications in coatings, catalysis, and electronics.

高晶α-氧化铝纳米颗粒的晶体学和形态表征：x射线衍射和透射电镜综合研究

采用新型沉淀法合成了高晶α-氧化铝（Al₂O₃）纳米颗粒，并通过x射线衍射（XRD）、透射电子显微镜（TEM）、能谱（EDS）和选择性区域电子衍射（SAED）对其进行了表征。XRD证实了六方刚玉相，晶格参数a=b= 4.7624 Å， c= 13.002 Å。利用多种模型对晶体尺寸、应变和能量密度进行了估计，得到晶体尺寸为56.92 nm。透射电镜显示54.35 nm的球形颗粒。EDS证实了纯度，SAED证实了高结晶度。这些纳米颗粒适用于涂料、催化和电子领域的应用。

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
