The Department deals with research and production of special products and alloys based on platinum and other precious metals. The main products are:

  • catalyst nets
  • thermocouples
  • laboratory dishes
  • Fisher and Winkler electrodes,
  • semi-finished products of gold and silver
  • semi-finished products of platinum

Catalyst nets:

  • Chemical composition: PtgRh5%Pd5%; PtRh10%
  • Wire diameter: ∅0.06 to ∅0.08 mm
  • Net diameter: ∅1,270 – 3,995 mm

They are applied in the chemical industry, in the process of nitric acid production.
