No-Cement Corundum Refractory Castables.
Novobilská, Martina ; Kovář,, Pavel (referee) ; Nevřivová, Lenka (advisor)
This thesis deals with the problem of no-cement corundum refractory castables. In the theoretical part, it focuses on NCC refractory and its use, production technology and input raw materials. The second part of the theoretical work deals with MgAl2O4 spinel. The practical part of the thesis then continues in the topic and focuses on cement-free refractory concrete and the influence of MgO content on their properties.

Thermal analysis methods application for characterisation of sol-gel binding system for ceramic materials
Cesnek, Ľuboš ; Másilko, Jiří (referee) ; Švec, Jiří (advisor)
The master thesis deals with the study of the binder system of silica sol and its characterization mainly by methods of thermal analysis. The master thesis also uses method of rheology to determine the gelatinization time, method of TG/DTA do analyse the exo and endothermic effects during heating, the method of FT-IR to quickly determine the composition of samples, method of XRD to analyze phase composition of the samples and the method of SEM to observe the topography of the samples. MgO is used as a gelling agent, reactive alimina is used as a filler.
