Abstract
The mechanism of transition of colloidal nanoparticles of metallic zinc obtained by pulsed laser ablation (PLA) of a metal target in liquid with different pH into zinc oxide directly during PLA and their storage has been considered. It is shown that the rate of oxidation of metallic zinc particles in solution depends on the rate of two partial electrochemical reactions interconnected by the electron balance, namely, the rate of formation of the ionized form of zinc and the ionization discharge of oxygen dissolved in water. It has been revealed that the rate of oxygen delivery through the Prandtl boundary layer is the limiting stage of the zinc oxide phase formation process. As well, a number of powder samples are obtained using the PLA of metallic zinc in weakly acidic, neutral, and alkaline aqueous media and drying of the resulting colloidal solutions; their composition has been analyzed. According to X-ray phase analysis, exposure to atmospheric oxygen leads to significant further oxidation of the obtained powders; however, a metallic phase was detected in the sample after PLA in an alkaline medium. Thus, varying the conditions of the PLA provides wide opportunities for obtaining a final product with a specific composition and properties.
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.
