Obtaining Nanodispersed Powders of Zirkonia. From Novation to Innovation

Section: Scientific and Technical Innovative Projects of National Academy of Sciences of Ukraine
Language: Russian
Abstract: Influence of MW radiation, pulse magnetic field and their combinations with ultrasonic processing on process of chemical synthesis zirconia nanopowder with the direct control of their structure, properties and influence of phase structure at various stages of reception of a powder is investigated. It is shown, that essential influence on dispersiveness of a zirconia powder is rendered by structure and the size of agglomerates zirconium hydroxide. Formed at processing by the MICROWAVE field and drying in PMF more friable structure of agglomerate collapses at action on it of ultrasonic fluctuations more easy. Received zirconia nanopowder with the set size of particles in a range 5–20 nanometers and a specific surface 40–140 m²/g, can be used for reception constructional, tool, functional and bioceramics, sorbents and catalysts.
Key words: nanotechnology, pilot production of oxide nanopowders, MW, PMF, ultrasound, nanodiagnostics, ceramics.
