MATS8AI

Properties and structures of ceramics

 

ECTS Credits :

Duration : 21 hours

Semester : S8

Person in charge:

Silvère BARRAT, Professor, silvere.barrat@mines-nancy.univ-lorraine.fr 

Keywords:

ionic pileup - sintering - densification - production - toughness

Prerequisites: 

Ionic liaisons - Binary phase diagrams

General objective :

Have a global view of ceramics industry and of their properties

Contents:

Materials Engineering is an Engineering Science that takes into account not only the chemical composition, the structure of materials, but also their mode of preparation in order to reach specific properties. In some industrial sectors, the structural properties of current ceramics can compete with metals or metallic alloys. This leads to the major development of high performance massive ceramics or composite ceramics.

The objective of this course is to know the main families of industrial ceramics in the large meaning of their definition. Starting from a structural description, giving a glimpse of forming processes, underlining the relation between production conditions and microstructures obtained and presenting reachable mechanical properties.

Abilities: 

Level

Description and operational verbs

Know

The main families of materials and particularly ceramics - origin of chemical liaisons and properties of ionic pileups - different processes of elaboration of ceramics.

Understand
 

Eutectic pileups -  ion size/ coordination polyhedron relation - sintering mechanisms of ceramics (thermodynamic and kinetic) - toughness of ceramics.

Apply 

Weibull statistical approach in order to evaluate the toughness of ceramics.
