Monitoring of corrosion of refractory lining
Taraba, Vojtěch ; Ptáček, Petr (referee) ; Opravil, Tomáš (advisor)
This bachelor’s thesis is focused on the monitoring of corrosion of refractory lining in the cement rotary kiln, chemical and mineralogical changes of the refractory and their influence on the lining properties. Magnesia-spinel refractories located in the lower transition zone are analyzed by X-ray diffraction, X-ray fluorescence, inductively coupled plasma optical emission spectrometry and scanning electron microscopy.

Elemental composition analysis of inorganic materials
Szmek, Václav ; Richtera, Lukáš (referee) ; Zmrzlý, Martin (advisor)
This work deals with elemental analysis of inorganic materials, that are presented by blast furnace slag and geopolymeric material containing fly-ashes. In the theoretical part there are explained principles of elemental analysis of inorganic materials. Ways of dissolution of samples, optical emission spectroscopy and electron microscopy with energy dispersive x-ray analysis are commented. In experimental part the ICP analysis of oxide standards is described. The standards were used for estimation of EDS-correction factors. Then follow the preparation, proving and use of standards in analysis of blast furnace slag. The work is finished by exact analysis of concentration profiles of elements in interface of phases in geopolymeric material.
