Objectives

Students are expected to have a solid background in ceramic materials, including the characterization techniques of ceramic powders, the mechanisms of mass transport and the thermodynamic and kinetic factors that lead to the densification of these materials. The different classes of sintering are also studied. The glassy materials are also addressed from the point of view of the mechanisms of formation, structure and preparation, as well as the phenomena involving controlled crystallization to obtain ceramic glass.

Learning outcomes and competences

Knowledge and competences may be summarized 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.
• Ability to perform group work.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

It is advisable that students have acquired the basic knowledge about ceramic materials that are studied at "EMII".

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 practical component is based on laboratory works, which is evaluated through the elaboration of a group report and an individual exam of this component.

Evaluation Type

Distributed evaluation with final exam

Eligibility for exams

Terms of frequency: minimum of 10 in the weighted average of the theoretical and practical components.

Calculation formula of final grade

Formula Evaluation: Final mark = 0.7* theoretical component + 0.3* practical component.

Examinations or Special Assignments

Not applicable.

Internship work/project

Not applicable

Special assessment (TE, DA, ...)

By taking a final exam, which will take into account with the practical laboratory component, using the same calculation method as a normal student.

Classification improvement

The classification can be improved by taking an exam on the theoretical component, also taking into account the classification obtained in the practical laboratory component.
