Objectives
To understand the structure of different ceramic crystals (oxides, nitrides and carbides having important technological applications) and the structure of silicate minerals used in the manufacturing of traditional ceramics.
To understand the structure of glasses and the principles for glass formation. To understand the
typical compositions of the main types of commercial glasses.
To understand the effect of temperature on the structural transformations of ceramic systems.
To understand the determinant parameters controlling ceramic microstructure (surface energy, interfaces and grain boundaries).
To understand the interelationship amonf structure-microstructure-properties of ceramics and glasses.
To determine the effect of temperature on the structural transformations that occur in a ceramic system.
To evaluate the experimental conditions that lead to glass formation from ceramic oxide starting materials.
To evaluate the effect of the structure and microstructure of a ceramic material on the final properties.
To evaluate the effect of the composition on the final properties of a glass.
To be able to make a correlation among the scientific knowledge.
To be able to discuss experimental data with a critical point of view
To be able to relate the scientific knowledge with specific technological applications.
Prerequisites
To get frequency to this discipline it is necessary to attend at least 2/3 of the pratical classes.

Teaching method
The discipline comprises theoretical classes, theoretical-practical classes or laboratories.
In theoretical classes, the subject is presented by PowerPoint presentations. Several case studies are also presented.
Theoretical-practical classes involve the resolution of exercises related with the matter presented in the theoretical classes.
Laboratorial classes involve the demonstration of experiences related with concepts already given both in theoretical and problem sessions.
Evaluation method
The assessement involves 2 written tests (T1 and T2) and/or Examen (E), complemented by the answers to questions related with laboratorial experiments (A). For each student the participation in lab classes is mandatory.
The students with a final grade N=0.5T1+0.4T2+0.1A , which is higher or equal to 9,5, do not need to be evaluated in a final examen.
If evaluation is made by a final examen (E) , the final grade N=0.9 E+0.1 A. For both cases, N must be equal or higher than 9,5 (in 20).
