Abstract

A comprehensive study of trititanium pentoxide Ti₃O₅ powder synthesized by reducing rutile TiO₂ powder in a hydrogen flow is carried out. The temperature stability limits of β-, λ-, and α-phases for the obtained Ti₃O₅ powder are studied. The values of permittivity of 11.0–12.5 and dielectric loss tangent of 0.39–0.45 are determined for β-Ti₃O₅ in the gigahertz frequency range for powder with an average particle size of 3–6 μm. The ability of a composite material based on radio-transparent thermoplastic polyurethane and 33% of β-Ti₃O₅ electromagnetic radiation-absorbing phase to absorb microwave radiation is investigated. The fundamental possibility of using the earlier developed technology for synthesizing β-Ti₃O₅ by reducing rutile TiO₂ powder in a hydrogen flow to create microwave radiation-absorbing composite materials based on β-Ti₃O₅ is demonstrated.

氢流还原金红石型TiO2粉体合成Ti3O5粉体的性能研究

对金红石型TiO2粉体在氢流中还原合成的五氧化三钛Ti3O5粉体进行了全面的研究。研究了制备的Ti3O5粉末的β-相、λ-相和α-相的温度稳定性极限。在ghz频率范围内，平均粒径为3 ~ 6 μm的β-Ti3O5粉末介电常数为11.0 ~ 12.5，介电损耗正切值为0.39 ~ 0.45。研究了射频透明热塑性聚氨酯和33% β-Ti3O5电磁辐射吸收相复合材料对微波辐射的吸收能力。证明了利用早期开发的通过在氢气流中还原金红石型TiO2粉末合成β-Ti3O5的技术来制备基于β-Ti3O5的微波辐射吸收复合材料的基本可能性。

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.
