Research Centre for the Intensification of Metallurgical Processes at High Pressures and Temperatures, High PT MET, was established through the POS CCE Program, Priority Axis 2 “Competitiveness through research, technological development and innovation” (project no. POS CCE 898/14038).

The main aim of the Centre is to improve the research capacity in order to increase the Institute’s competitiveness based on innovative and environmentally efficient technologies in the field of science and engineering of non-ferrous materials.

Main technological goals:

  • implementation of emerging technologies for processing non-ferrous metal powders and their compounds in order to increase the value chain from resources to applications;
  • synthesis and micro-encapsulation of ceramic and hybrid nanopowders with predesign composition and morphology by hydrothermal/solvothermal/spray drying methods
  • reducing the consumption of materials, especially critical materials, by obtaining films and coatings with controlled properties;
