Abstract
The mineral composition, petrographic structure, and magnetic properties of artificial glasses obtained from high-temperature melting of mixtures of rocks of various geneses (volcanic–sedimentary rocks, quartzite–shales, and psammite–silt–pelite complexes) are studied. When glasses were synthesized, cooling and glass transition conditions of various durations were used. The formation of ferrimagnetic minerals is due to the composition of the stock and the cooling rate of the melt. The resulting magnetic particles during “fast” cooling are mainly in the superparamagnetic state (up to 90% or more of the total amount of the magnetic phase in a sample). A mixture of particles of different sizes is formed during “slow” cooling and, as a result, in different magnetic states: from superparamagnetic to the low-domain state. The ferrimagnetic phase that crystallizes in artificial glasses is as chemically heterogeneous iron oxide aggregates, mainly non-stoichiometric magnetite.
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.
