Study of the development of Alite crystallinity
Lakomá, Karolína ; Fridrichová, Marcela (referee) ; Dvořák, Karel (advisor)
The bachelor thesis summarizes current knowledge in the field of preparation and various influences on the structure of alite in triclinic modification. The work is mainly focused on the study of the development of crystallinity during heating and short isothermal endurance. Within the work, the production of pellets is optimized and the functionality of the experimental furnace for firing triclinic alite is verified.

Use of X-ray diffraction analysis in the optimization of cathode material syntheses for Li-ion batteries
Kunz, Marek ; Čech, Ondřej (referee) ; Chladil, Ladislav (advisor)
This thesis deals with study of structural changes in electrode materials prepared by spray-dry synthesis at different calcination temperatures using X-ray diffraction analysis. In the theoretical part, the work deals with the principle of XRD, parameters that influence the resulting diffractogram and Rietveld analysis. The part further deals with possible syntheses of cathode materials, calcination, and possible ways of battery degradation. The experimental part focuses on investigating the ideal calcination temperature and time of prepared cathode material samples.
