Course content

This course provides an overview of the properties, manufacturing and design of ceramics, nanostructured ceramics, films and coatings. Three main topics are covered: Properties, manufacturing processes (bottom-up and top-down approaches) with emphasis on achieving the desired properties as well as the basis for design. Properties: Bulk: elasticity, hardness, strength, fracture toughness and creep in relation to composition and micro- and nano-structure (grain size, secondary phases, porosity) and thermal properties. Films/coatings: mechanical performance. Manufacturing: Synthetic ceramic powders, the stabilization of dispersions, forming by pressing, casting, extrusion and injection molding, sintering and heat treatment. Deposition of films and coatings. Design: Principles of design with brittle materials, Weibull statistics, analysis of fracture and toughening of ceramics. Finite size effects in ceramic materials.

Learning outcome

After completing the course the student will be able to:
- Explain the definition of physical properties of ceramic materials (density, heat capacity, thermal conductivity, thermal expansion) and describe which parameters these properties are dependent on.
- Explain concepts related to mechanical properties of ceramic materials (elasticity, Young's modulus, theoretical strength, tensile strength, compressive strength, bending strength and fracture toughness) and understand the relationship between fracture strength and defects in the material.
- Explain how the mechanical properties of ceramics are measured, make calculations about this and explain how the properties of ceramic materials differ from other types of materials (eg metals).
- Describe the mechanisms of plasticity in ceramic materials.
- Make simple failure analysis of ceramic materials.
- Understand how ceramic materials behave when used at elevated temperatures (creep and thermal shock resistance), understand how they react with ambient gases and liquids and calculate the typical parameters from the creep data.
- Explain the principles that must be used for designing with ceramic materials, how they differ from other materials and perform calculations of Weibull statistics.
- Explain the toughening mechanisms available and explain how these can be used to increase the fracture toughness of ceramic materials.
- Describe the process of how ceramic materials are produced from powder synthesis to the firing of the green bodies to achieve a dense material.
- Describe processes for the preparation of ceramic films and coatings
- Understand the importance of how the preparation process affects the properties of the finished product.
- Describe typical properties of different ceramic materials and compare these with other types of materials.
- Describe how glasses and glass ceramics are prepared.
- Understand how finite size effect influences the properties of ceramics

Learning methods and activities

The teaching is based on lectures, exercises and an obligatory project work. The exercises are not mandatory. Since the teaching is given in English the Examination will be given in English only. Students are free to choose Norwegian or English for written assessments. Expected time spent on this course: Lectures: 60 timer, Project work: 55 timer. Exercises: 26 timer. Self studies: 70 timer"

Compulsory assignments

  • Project assignment

Further on evaluation

Final grade in the course is based on portfolio assessment. The portfolio includes digital written final examination (75 %) and a mandatory project work (25 %). The evaluation of the different parts is given in %-points while the final grade for the whole folder is given by a letter grade.
If there is a re-sit examination, the examination form may change from written to oral. The student does not need to redo an approved project work.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
