Ceramic and colloidal processing

Summary

The course covers the production of ceramics and colloids from the basic scientific concepts and theories needed to understand the forming processes to the mechanisms and methods of sintering (firing) ceramics. Including the scientific principles behind the formation of colloidal dispersions.

Learning Outcomes

By the end of the course, the student must be able to:

• Apply The acquired notions of the dispersion of particulate matter for any application.
• Produce Acquired the knowledge, skills and practice necessary to produce a ceramic in an industrial environment or a laboratory
• Choose to produce a ceramic of a particular geometry in connection with an application.
• Demonstrate the colloidal stability of a suspension using the DLVO theory.
• Describe the key characteristics of a ceramic powder needed to make a ceramic
• Explain the mechanisms behind the different sintering phenomena.
• Describe the different methods of synthesizing a ceramic powder.

Transversal skills

• Use both general and domain specific IT resources and tools
• Take responsibility for health and safety of self and others in a working context.
• Negotiate effectively within the group.

Teaching methods

Lectures and exercises in class (3 h). Exercises with calculation will be done in class and they will serve as typical example of questions during the oral exam. Nevertheless, during the oral exam no calculations will be required but a clear understanding of concepts and the logical connections of the arguments of the course.

Expected student activities

Attendance of lectures, doing exercises during class and at home, reading written material, discussion in class.

Assessment methods

The final grade is attributed based on the final oral exam.
