Objectives

The objective of the course is to give technologic informations on ceramic materials for engineering applications. Students shall receive informations on many production processes for several ceramic materials starting from the raw materials used. The fired materials will be compared in terms of mechanical and thermal properties. During the course some advanced ceramics will be studied and their properties reported.

Acquired skills

- To know the complete properties of ceramic materials.
- To know the application fields of the different typologies of ceramics.
- To know the limits of ceramics when applied as engineering materials.
- To evaluate how to substitute some traditional engineering materials with specific ceramics.
