Description:

The Ceramics Division started its research activities in areas of synthesis, characterization and evaluation of ceramic materials for electronic and biomedical applications. In later years, research lines on structural ceramics, composite materials, magnetic ceramics, hybrid coatings, mechanochemistry reactions and supercritical fluid technology were incorporated.

Research lines:

  • Development of organic-inorganic hybrid coatings
  • Development of nanostructured ceramic for electronic applications
  • Composite materials of high dielectric constant
  • Lead-free piezoelectric and relaxor materials
  • Processing of porous ceramic materials
  • Development of ceramic materials formed by 3D printing technologies
  • Mechanical behavior of advanced ceramics, in dense and porous grades, and refractories, at room temperature and high temperatures
  • Gaseous and liquid slag corrosion of refractory materials
  • Mechanochemical synthesis of functional ceramics
  • Magnetic and multiferroic materials based on transition metal oxides
  • Development of nanostructured composite biomaterials
  • Development of bone cements based on calcium phosphates
  • Supercritical fluid technology application to the development and processing of biomaterials
  • Treatment and reuse of waste applied to ceramic materials
