Refractory Μaterials

The subject concerns the basic course in the Technology of Refractory Materials.
The content of the course initially includes the presentation of the refractory materials and their classification followed by an analysis of the properties of these materials and the relevant tests. Then the most significant categories of refractory materials are presented and discussed.
During the semester, the students attend laboratory exercises and deliver the relevant reports for deepening into the subject and developing skills. The cooperation and the development of critical thinking are also encouraged.
