The laboratory studies the behaviors of materials with temperature changes. By measuring the temperatures and heat fluxes correlated with thermal transitions in the materials under study, the changes that correspond to a change in their structure, composition and phase state are determined. Thermal analysis which allows the study of weight and phase changes in the composition of the metal/metaloxide nanoparticles in bulk or supported on porous materials during the thermal treatment in different gas media (inert, oxidative, reductive) is performed. The detailed characterization of the materials used as catalysts is a prerequisite for achieving highly efficient clean technologies. Potential partners and customers of the laboratory could be research teams and companies developing and producing new materials in various industries.


The available instruments can be used to:


The services offered are:


Differential scanning calorimeter DSC 404 F3 Pegasus working in a wide temperature region from  -150оС to 1600оС suitable for determination of heat capacity.

The apparatus for thermogravimetric analysis STA449F5 Jupiter of NETZSCH Gerätebau GmbH allows combined TG/TG-DSC and TG-DTA measurements. The system has a top loading with a vertical design and working with samples from 3 mg to 35 g and a resolution above 0.1 μg with a rate of 0.1 to 50oC/min. The apparatus is equipped with a vacuum pump to evacuate the working space and can operate in different gas media: inert, oxidative, reductive, with automatic gas control with a built-in controller to deliver a minimum of 2 gases, adjusted by pressure and flow rate (from 5 to 250 ml/min with a resolution of 1 ml/min) simultaneously.
