Purpose of the development: The Ukrainian institute using the methods of "soft chemistry" developed a technology that allows you to create a wide range of nanomaterials solutions using controlled phase formation processes (colloidal synthesis, sol-gel method, synthesis in microemulsions at temperatures to 90-95 ° C).

Recommended application field: - Raw materials for the chemical industry, production of glasses and glass ceramics; durable abrasives; - Structure-forming additives for hardening metals and alloys; - Components for ultra-hard, high temperature, wear-resistant, homogeneous and inert ceramics; - Raw material for optical ceramics (laser, scintillation, fluorescent); - Photonics, plasmonics, sensing, catalysis, medicine.

Technical characteristic: The technology of obtaining slaboaglomerirovannyh nano particles of different morphology (monosized spherical particles and combined with the structure of "core / shell", isometric particles with low dispersion in size) on the basis of: - Rare earth oxides Lu2O3, (Lu (1-X) EuX) 2O3, Y2O3, (Y (1-X) NdX) 2O3; - Refractory oxide Y3Al5O12, (Y (1-X) 3NdXAl5O12; - Particle structure "SiO2 core / shell Lu2O3, (Lu (1-X) EuX) 2O3"; - Particle structure "SiO2 core / shell ZnO, PbS, Au, Pt, Pd". Obtain stable sols of precious metals Au, Pt, Pd. The methods of stabilizing nanocrystals of these metals to prevent agglomeration during the formation of mono- and multilayers on various substrates.

Advantages over analogues: The advantage of this technology is the possibility of obtaining nanopowders with controlled composition, particle size and shape with a low degree of agglomeration.

The development stage readiness: Ready for application

Description of the development:
()
The technology is environmentally friendly, it allows to obtain nanoparticles of various chemical compounds (metals, alloys, oxides, chalcogenides, etc.) And with high reliability to control their composition, structure and geometric characteristics. The main stages of the process are: Preparation of a chemical coprecipitation method from aqueous solutions of amorphous precipitate precursor, drying and crystallization of low-temperature annealing process at temperatures up to 1000-1100 ° C. The developed technology allows monosized particles already at the stage of formation of the amorphous precursor. Either traditional technology - receive polydisperse amorphous precipitate and, if necessary, be isolated from a fraction with a narrower particle size distribution ultracentrifugation techniques and / or sedimentation.
