Preparation of large and complex-shaped ceramics parts
Prehradná, Jana ; Pouchlý, Václav (referee) ; Trunec, Martin (advisor)
This bachelor’s thesis deals with research of ceramic materials in field of material engineering. The first part deals with biomaterials, especially bioceramics, its types, properties and its usage. The second part of this thesis deals with transparent ceramics and the third part includes the procedure and method of gel casting. The experimental part is dedicated to production of large and complex shaped components - knee joint, spherical cover and discs with transparent properties. The method of gelcasting was used for samples preparation of this type. The task was not only to produce these samples, but also to find suitable surrounding conditions for the proper course of the entire production process.

Gelcasting of Advanced Ceramics
Veselý, Jan ; Maca, Karel (referee) ; Trunec, Martin (advisor)
In Bachelor thesis, a literary overview of gelcasting method was worked out and pursuant to this overview, composition of alumina suspension was optimised for fabrication of bulky and complex-shape ceramic part. Four variants of ceramic powder filling in suspensions were prepared. Based on the experiments, a suspension with powder loading of 47,5 vol. % was chosen. The ratio between linear and crosslinking monomers was investigated for this suspension. A suspension with monomer ratio of 4 : 1 (linear : crosslinking) was chosen for preparation of bulky and complex-shape ceramic part. Gelcasting was verified by fabrication of ceramic medal and a knee-joint.
