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.

Design of a porcelain set for additive manufacturing
Vítek, Jan ; Haltof, Vladimír (referee) ; Škaroupka, David (advisor)
This bachelor thesis deals with the design of a set of porcelain coffee cups. The principles of parameterization are used in the design, as well as an innovative way of creating decor using generative algorithms. The thesis examines the possibility of using additive technologies in the production of porcelain products, both in the production of molds and in the direct production by SLA technology. It also includes the development of material for 3D printing from porcelain and finding suitable process parameters for printing.

Testing of Surge Arresters
Jeřábek, Lukáš ; Paar, Martin (referee) ; Krbal, Michal (advisor)
This bachelor's thesis is devoted to metal oxide surge arresters. After historical and theoretical introduction, which explains their principles and describes their characteristical properties, analysis of the standard IEC 60099-4 and testing according to the standard with focus on the type tests follows. This chapter is also amended with review of the standard's imperfections and with its most probable future development. The work concludes with a market survey, a review of the largest manufacturers and a comparison of their products.

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.

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.

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...
