Objectives

Justification: Knowledge on ceramic materials is a fundamental tool on materials engineering courses at the college degree level, due to its enormous importance in numerous industrial applications. Objectives: This subject aims at studying issues that involve powder characterisation, mechanical consolidation processes and sintering mechanisms of ceramic materials. Glasses are also studied from the point of view of the principles of glass formation, structure and fabrication processes as well as controlled crystallisation methods to obtain glass ceramics materials. Relationships involving structure-properties-processing is a fundamental guideline throughout the course.

Learning outcomes and competences

Knowledge and competences may be summarizes as follows:

 

- Solid fundamentals on ceramic and glass materials, from design to processing technologies

- Application of studied basics concepts to the development of new ceramic and glass materials.

- Capacity to develop group work and oral presentation of the obtained results.

Teaching methods and learning activities

The teaching methodology allows students to actively participate in the knowledge acquisition in close collaboration with teacher in order students can obtain full comprehension of the studied subjects. It is strongly promoted the autonomous learning, initiative and entrepreneurial spirit. Slide projection is the main means used by teacher. The experimental component of the subject is essentially composed of some laboratory works, bibliographic surveys and visits to industrial companies. At the end of each experimental work a written reported is elaborated.
