Teaching description

Teaching program is provisional and may be subject to changes

Students are requested to retrieve chemistry, physics, materials fundamentals, electromagnetism

The course provides a thorough understanding of ceramic and glassy materials. The student will be able to assess whether, when and how to suggest the use of ceramic materials in different application contexts. The criteria for the engineering design and affidabilistic approach on ceramic materials will be disclosed.

The course should enable the students to: 

* Identify the role of ceramic materials in technological devices and in everyday life.

* Identify the functional and structural properties of ceramic materials and learn how to recognize their properties starting from sensory perceptions ending up to analytical testing.

* Quantify the engineering performance of ceramics: strength, stiffness, toughness, transparency, opacity, refractoriness, thermal and electrical conductivity and certify their suitability for specific uses.

* Acquire a working method for the identification of the material and combination of materials capable of offering the best engineering solution

The course includes plane lecturing on scheduled program plus laboratory experience, ceramic forming and sintering design by rapid prototyping, sol-gel slip casting

Attention will be given to applications and markets: ceramics for aerospace, electronics, medicine, energy, glass technology

Guided tours in research laboratories and companies are a part of teaching method

An introduction on resources resource scouting will be give: Databases, internet, fairs, books, magazines, exhibitions

  Meet experts in seminars

The student is evaluated by the commitment and interest with which he follows the theoretical lectures and laboratory experiences. The student at the end of the course will prepare a monograph or a report on experiences of laboratory. A final oral examination will give the final vote.
