Sands for the production of foundry moulds and cores
Fúsek, Jakub ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
Bachelor thesis deals with survey, properties and usability of the most common foundry molding sands. The most common sands are silicas for their economical. In particular, sands used in the Czech Republic are described, there is also a sand quarry with non-Europe distribution. Sadly, they have also many defects which limit to their use. In these cases we use non-silica sands. The most popular non-silica sands are outlined, including currently expanding synthetic sands. There are also listed some basic data and properties, for example, fitness for purpose.

Foundry sands and their properties
Odložil, Jan ; Nezvalová, Hana (referee) ; Rusín, Karel (advisor)
Bachelor thesis describes advantages and disadvantages of base sands used in foundries. The most popular base sands are silicas for their economical and size fraction. They have also much defects as discontinued heat dilatation, acidit reaction and silicosis. Non-silica base sands have not this disadvantages, but they are more expensive. Some foundries have started applying new synthetic non-silica base sands in recent time, which are chemically neutral and the casting quality is high.

Sands for the production of foundry moulds and cores
Ostrézí, Filip ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
Bachelor thesis deals with properties of most usable sands in foundries and with their advantages, disadvantages and usability. Most used are silica sands, because of their low prices, but they have a lot of disadvantages like discontinued heat dilatation, acidit reaction and health defect. Mainly described are sands from Czech and Slovak Republic and few sands out of Europe. Non-silica sands don´t have so much disadvantages, but their problem is a big price. Most used non-silica and synthetic sands are described.
