List of available PhD theses

Analysis of batch-to-glass conversion process

Department: Laboratory of Inorganic Materials, Faculty of Chemical Technology
Theses supervisor: Ing. Richard Pokorný, Ph.D.


The goal of this project targets the analysis of one of the critical batch-to-glass conversion processes – the evolution and collapse of the primary foam at the batch-melt interface. This porous foam layer, which behaves as a form of insulation layer, results from the products of various gas evolving reactions that are being trapped in the primary melt. This project will focus on understanding the foam morphology, the reactions that lead to primary foaming.

Melting processes in vitrification technologies

Department: Laboratory of Inorganic Materials, Faculty of Chemical Technology


The analysis of the processes during the vitrification process is performed using a mathematical model. Input data of the model will be obtained by a set of experimental methods including high temperature monitoring of melting processes, analysis of released gases, thermal analysis and determination of oxidative reduction equilibrium in melts.

Special glasses

Department: Laboratory of Inorganic Materials, Faculty of Chemical Technology
Theses supervisor: Ing. Petr Kostka, Ph.D.


The work will focus on the preparation and study of new glasses containing heavy metal compounds, especially heavy metal oxides. Heavy metal oxide glasses in which the glass network is formed by oxides such as e.g. TeO2, GeO2 or Sb2O3 instead of SiO2 are studied for their characteristic properties. In comparison to conventional glasses they particularly excel with their wide transparency interval reaching to much longer wavelengths than in silicate glasses, higher refractive index, and non-linear optical properties. They are also interesting because of the high quantum yield of radiative transitions of rare earth ions embedded in their glass networks, which have low phonon energies, and because of their ability to adopt high concentrations of rare earths ions. The characterization of the prepared materials will include determination of their basic physicochemical properties such as density, molar volume, thermal stability, chemical resistance, hardness, optical transparency, refractive index etc. The correlation between the structural units of the glass network and resulting properties will be investigated and the influence of technological conditions during glass preparation on glass properties will be studied. The Laboratory cooperates with foreign research institutions.
