Abstract

The properties of ceramics obtained by sintering of compacts from ultrafine and microfine aluminum oxide powders in a constant magnetic field were studied. Aluminum oxide activation sintering in a constant magnetic field makes it possible to reduce the sintering temperature of ceramics while simultaneously improving its quality. It was found that the effect of the magnetic field is most pronounced when sintering compacts from micropowders. It was determined that the density, microhardness, and tensile strength significantly exceed the corresponding values established for ceramics obtained by sintering of compacts of ultrafine aluminum oxide in a magnetic field.

氧化铝粉体粒度对恒磁场烧结陶瓷的影响

研究了超细和微细氧化铝粉在恒磁场作用下的烧结性能。恒磁场下氧化铝活化烧结可以降低陶瓷的烧结温度，同时提高陶瓷的质量。研究发现，磁场的影响在微粉烧结时最为明显。结果表明，该材料的密度、显微硬度和抗拉强度明显超过了在磁场中烧结超细氧化铝压块所得到的陶瓷的相应值。

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.
