Recommended application field: Power Engineering - SOFC, thermal stable coatings for turbine blades; Mining Industry - rods, plungers, injectors; Chemical Industry - parts of pumps (breechblocks, valves, plungers) injectors, milling balls, catalysts, sorbents; Metallurgy - refractory structural elements, cutting tools, guides, crucibles; Medicine - prosthetic appliances, filters, ion-exchangers, UV-protect, capsules.

Advantages over analogues: The main advantages of our technology are: - more narrow particle size distribution; - lower degree of agglomeration; - predermined particle sizes in the range of 5 to 50 nm; - high homogenious component distribution; - low synthesis temperature (400-700 C); - eliminating the mechanical grinding stage; - easy scale-up in manufacturing; - low sintering temperature (1250-1350 C); - high performance of ceramics including homogenity, stability and durability; - lifetime of ceramics mine pump plunger from zirconia nanopoweders is 15-20 times longer than usually; - production of precise articles and films; - lower cost, environmentally friendly; - lower energy consumption.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
Technology of obtaining oxide nanopowders with speci-fied chemical, phase and granulometric composition is based on wet-chemicals methods with the use MW radiation, pulse magnetic field and ultrasonic for agglomeration prevention. We obtain ZrO2 (0-8% Y2O3) powders with predetermined particle size in the range from 5 to 30 nm, narrow size distribution and specific surface area 140-20 m[2]/g, respectively with soft agglomerates for ceramics, compros-i-tes and SOFC applications. We obtained TiO2 (anatase) powders with predetermined particle size in the range from 5 to 25 nm, narrow size distribution, specific surface area from 150 to 50 m[2]/g and soft agglomerates for catalyst and UV-protects andTiO2 (rutile) powders with particle size 30-50 nm. We obtained LaSrMnO3 powders with narrow size distribution (12-15 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 also obtain zirconia and/or alumina ceramics with small grains for wear-resistant, structural, instrumental and fuctional applications. Porous ceramics obtained can be used in medicine, catalysts, filters and SOFC electrodes. We can obtain composites with metal, ceramics and polymer matrix. We obtain PZT ceramics.
