TECHNOLOGY OOFF OBTAINING THE OXIDE NANOPOWDERS WITH SPECIFIED CHEMICAL,, PHASE AND GRANULOMETRIC COMPOSITION,, CERAMICS AND COM(cid:2)(cid:2)POSITES OONN THEIR BASE INNOVATIVE TECHNOLOGIES Description Technology of obtaining the oxide nanopowders with specified chemical, phase and granulometric composition based on wet(cid:2)chemicals methods with using MW radiation, pulse mag(cid:2) netic field and ultrasonic for prevention agglomeration. We obtain ZrO2 (0(cid:2)8% Y2O3) powders with predetermined par(cid:2) ticle size in range from 5 to 30 nm, narrow size distribution and specific surface area 140(cid:2)20 m2/g, respectively with soft agglomerates for ceramics, composites and solid oxide fuel cell (SOFC) applications. We obtained TiO2 (anatase) powders with predetermined par(cid:2) ticle size in range from 5 to 25 nm, narrow size distribution, specific surface area from 150 to 50 m2/g and soft agglomer(cid:2) ates for catalyst and UV(cid:2)protects and TiO2 (rutile) powders with size (30(cid:2)50 nm). We obtained LaSrMnO3 powders with narrow size distribution (12(cid:2)15 nm) and bimodal size distribution (40, 200 nm) for magnetic sensors and SOFC cathodes. And other oxide powders (PZT, Al2O3 based, for example). We have a pilot line for nanopowders obtaining. We obtain zirconia and/or alumina ceramics with small grains for wear(cid:2)resistant, structural, instrumental and functional appli(cid:2) cations. We obtain porous ceramics for medicine, catalysts, fil(cid:2) ters and SOFC electrodes. We can obtain nanocomposites with metal, ceramics and polymer matrix. We obtain PZT ceramics. Innovative Aspect and Main Advantages:: Our technology in compare with other one ensure: • more narrow particle size distribution; • lower degree of agglomeration; • predetermined particle sizes in the range of 5 to 50 nm; • high homogenious component distribution; • low synthesis temperature (400 (cid:2) 700 C); • eliminating the mechanical grinding stage; • easy scale(cid:2)up in manufacturing; • low sintering temperature (1250 (cid:2) 1350 C) • high performance of ceramics including homogenity, sta(cid:2) bility and durability; • lifetime of the ceramics mine pump plunger from zirconia nanopowders is 15(cid:2)20 times longer than usually • production of precise articles and films; • lower cost, environmentally friendly • lower energy consumption.
