Donetsk Institute of Physics and Engineering in Hohor of O.O. Galkin, NASU

General Information

Donetsk Institute of Physics and Engineering of National Academy of Science of Ukraine has many years of experience in the areas of materials processing and properties development. The focus has been to study the influence of doping, deformation (severe plastic deformation, cold hydrostatic pressure), temperature and other parameters on materials structures. In the former Soviet Union, the institute was a leader in the field of physics and technology of high pressure. The studies in the material science department included ceramics and metallic materials. For more than 10 years, the Institute was involved in the study of the influence of various physical influences (microwave, pulse magnetic field, ultrasonic, high hydrostatic pressure and others) on the formation of oxide materials nano-particles. The study focused on the formation, phase and structure transition, densification and properties. The research effort was carried out under government, academic, international and direct contracts.

Focus and Expertise

  • Physics and Technology of promising materials. Nano-materials and nano-technologies: investigation of the nano-particle formation in oxide systems in the course of chemical synthesis using intensive physical actions (microwave action, pulse magnetic fields, ultrasound, high pressures); investigation of structural heterogeneity and multiscale phenomena in complex systems of the AB03 and AO2.
  • Phase transformations. Structure and properties: investigation of an influence of a structure state and a size of structural elements on the mechanisms and regularities of phase transformations in ceramic oxide materials; investigation of martensite transformations in response to mechanical stresses.

Applied researches

The technology of obtaining of oxide nanopowders was created on base of fundamental investigations. With the help of X-ray analysis, TEM, NMR and EPR, IR-spectroscopy, computer simulation there have been found out the main mechanisms and determined the formation peculiarities of zirconia dioxide nano-crystals from an amorphous hydroxide.


The products of developed technology are zirconia (Zr02)(0...8 mol % Y203) powders with determined particle size in the range from 5 to 30 nm, narrow size distribution and specific surface area 140...20 m2/g, respectively, with soft agglomerates. The technology has been used to obtain titania (Ti02), lanthanum doped manganite (LaMnOs) powders and other oxides. The technology prevents agglomeration and provides specified chemical, phase, granulometric composition and modified surface of nanopowders. The technology of production of high-density and porous ceramics on the basis of developed zirconia nanopowder, as well as on the basis of alumina and other oxide nanopowders, has been also worked out. The developed forming technology allows mechanical processing of green ceramics and obtaining complex and precise high-strength parts and films. Nanostructural zirconia ceramics does not tend to degradation (water vapor atmosphere, 150-180°C).

Innovative Aspect and Main Advantages

Nanopowder production technology has a number of significant advantages:

  • enhanced characteristics of nanopowders,
  • high homogeneous component distribution,
  • elimination of mechanical grinding stage,
  • low sintering temperature (1250 - 1350°C), and
  • low cost.

Nanopowder ceramics products have high grain homogeneity, strength, thermal and chemical stability and durability. Industrial tests proved considerable (from 20 to 40 times) extension of operation time of zirconia nonstructural ceramic parts (mine pump plungers, water descaling nozzles).

Areas of Application

  • Oxide nanopowders are used in chemical industry; as components of composites; and also as raw materials for structural, instrumental and functional ceramics.
  • Power Engineering: Solid Oxide Fuel Cells (SOFC) electrolyte, anode and cathode.

  • Chemical Industry: parts of pumps (breech-blocks, valves, plungers); injectors; milling balls; catalysts, sorbent agents and pigments, etc.
  • Metallurgy: nozzles, refractory structural elements, cutting tools, guides, crucibles. Structureand size distribution of Zr02 - 3mol% Y2O3 nanopowders.
  • Nanostructural ceramics parts.
  • Electronics: insulators, dyes for light guides, sensors.
  • Environmental protection: water purification and desalination materials.
  • Medicine: biocompatible dental and orthopedic prosthesis, ion-exchangers, UV-protectors, antibacterial coatings, capsules for drug delivery, test materials.

Stage of Development

  • Available for demonstration and independent testing
  • Nano-powders pilot production line is available. Ceramics pilot production line is being organized.
