Characterization of brick clays for the production of THERM bricks
Svobodová, Markéta ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
The Bachelor´s thesis is focused on the comparison of brick claysthat arecalcium and non-calcium and then it determines which of these brick clays are suitable for production of thin wall thermal insulating fittings called THERM. The main influence has CaO contained in the calcium brick clay in the form of calcite. In the theoretical part you can find an overview of the brick clays in the Czech Republic and abroad then requirements for clays and laboratory testing of bricks. In the practical part of the work were performed tests on samples of brick clays used in the Czech Republic. Mineralogical composition differenceis obviousafter firing the brick clays.This difference is caused by occurrence of anorthite calcium brick clay which then reflects in the usefulproperty of brick shard. Based on these tests I make evaluationof the most suitable type of brick clay for processing the THERM fittings.

Development of anorthite ceramics
Toman, Boris ; Šveda,, Mikuláš (referee) ; Sokolář, Radomír (advisor)
When firing calcium ceramic materials creates a new crystalline phase anorthite. It can significantly improve the properties of ceramic body. This work deals with the possibilities of development anortitové ceramics using non-plastic raw materials, particularly alumina cement compared with conventional ceramics based on mullite.

Results of Anorthite Creation in ceramic Body
Beránková, Karla ; Šveda,, Mikuláš (referee) ; Sokolář, Radomír (advisor)
Anorthite is crystalline phase in the ceramic body. Is acquired on burning a mixture of calcium ceramic raw material. This work deals with the influence on the resulting properties of anorthite ceramic body, especially flexural strength, porosity, shrinkage, thermal expansion coefficient. And the influence of different CaO sources on the properties. As a source of CaO was used calcium carbonate, calcium hydroxide and fluid fly ash.
