Abstract

The influence of the oxide layer thickness on the oxygen content in AlN powders synthesized at the ISMAN pilot plant using the self-propagating high-temperature synthesis (SHS) is studied. Experimental studies of the obtained powders to determine particle size, phase composition, and morphology are carried out using X-ray diffractometry and scanning electron microscopy. The obtained results make it possible to compare the calculated and experimental data on oxygen content. The influence of the oxide layer thickness and particle size on the total oxygen content in AlN powder is shown. The average oxygen content for aluminum powders with an average particle size of 1–7 μm is calculated depending on the thickness of the oxide layer. The presented model and results can be used to optimize the production and processing of AlN powders in order to minimize the impurity content and improve their performance characteristics.

氮化铝粉中最低氧含量的研究

研究了在ISMAN中试装置采用自传播高温合成（SHS）法制备的AlN粉末中氧化层厚度对氧含量的影响。利用x射线衍射仪和扫描电子显微镜对所得粉末进行实验研究，以确定粒度、相组成和形貌。所得结果可以将氧含量的计算值与实验值进行比较。研究了氧化层厚度和晶粒尺寸对AlN粉末中总氧含量的影响。根据氧化层厚度的不同，计算了平均粒度为1 ~ 7 μm的铝粉的平均氧含量。该模型和结果可用于优化AlN粉末的生产和加工，以尽量减少杂质含量，提高其性能特性。

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
