The Effect of Nanofibres Dispergation on the Properties of Sintered Ceramic Body
Němec, Tomáš ; Keršner, Štěpán (referee) ; Sokolář, Radomír (advisor)
The main goal of this diploma´s thesis is to review final qualities of traditional porcelain body with using nanofibers. The theoretical part of the thesis summarizes the current knowledge of the research on ceramic composite with using nanofibers. The vast majority of these researches is engaged by reinforcing technical ceramics, on the other hand area of traditional porcelain is still unexplored area. Besides that there are shown technological ways of the production and dispersion of the most important types of nanofibers. In the practical part of this thesis is experimentaly defined the most effecient way of homogenization procedure and the most effecient dose of nanofibers for pure kaolin body. In conclusion are compared the resulting properties of traditional porcelain body with using Al2O3 and SiO2 nanofibers.

Svatojiřská legenda a její odraz v porcelánovém papírmaše
HEJDUSOVÁ, Aneta
The diploma thesis deals with the legend of St. George, deals with its processing in the Renaissance Florence and presents monuments with this motif from Italy and Czech territory. The aim of the diploma thesis is the interconnection of the theoretical and practical part. Inspiration became the ceramic reliefs made by Renaissance artists, in particular the della Robbia family. The work will be supplemented by an unconventional technique of processing porcelain paper with the motive of St. George. The theoretical part discusses the life of St. George, deals with the mission of the saint and tells the legendary story of victory over the dragon. Also included are documents that provide a deeper analysis of the legend of St. John the Baptist, as well as the iconography that discusses the St George's legend from the point of view of Christian beliefs. In the practical part, the theoretical part will be used for the processing of composite material from paper and porcelain with motive of St. George the dragonslayer.

Greek and Roman Influences in Creamware and Porcelain from Czech Lands from the End of 18th Century and First Half of 19th Century
Minaříková, Adéla ; Ondřejová, Iva (advisor) ; Mergl, Jan (referee)
The technique of manufacturing of creamware and porcelain was discovered in Europe during the 18th century. The objects made from these materials document the social changes and the development of the dining culture, which both occured during the 18th century. At the end of that century classical culture became a fundamental inspirational source, which had been supported both by the discoveries of the ancient towns, Pompeii and Herculaneum, and by publishing books presenting ancient art. From the end of the 18th century the creamware and porcelain objects were started to be manufactured also in the Czech lands. In this master thesis I have studied, how the ancient influences were manifested in the products of the Czech and Moravian factories, from where they came and how they were transformed. The thesis does not cover all porcelain and creamware production, however it focuses on those factory where it was possible to detect ancient influences. The approach of the particular factories was strongly different. Czech porcelain factories took over ancient themes more likely from graphic patterns used in European workshops. The shapes derived from ancient pottery do not differ too much from the older and also contemporary European examples which were used as models. However, creamware objects tried, nesides the...

The Possibilities of innovation of the sanitary ceramics body
Čech, Tomáš ; Chudomelka, Josef (referee) ; Sokolář, Radomír (advisor)
The aim of this thesis is to assess the possibility of increasing utility properties shard of sanitary ceramics. Description the current production of sanitary ceramics. Assessing of the impact steatite admixture into existing raw material mixture for the production of sanitary ceramics firing body characteristics (porosity, strength, thermal expansion) using the available scientific literature. Proposition the optimal dose of steatite material into the raw mixture. Evaluation of physical and mechanical properties of the resulting products of this recipe.

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.

Kvaššay, Ivan ; Šaroch, Stanislav (advisor) ; Bič, Josef (referee)
The main aim of this bachelor thesis is to map and analyze the information about chinese emigrants in western coutries focusing on the student community. Another aim is to analyse their return to China after they finish their studies on western universities or after their works in various areas for example management, engeneering and so on.
