| Course contents : | 1. Introduction
- definition: ceramics - refractory materials - composite materials
2. Powders: production methods
- extraction processes
- synthetic powders: precipitation - vapour phase reaction - sol-gel procedure.
- main characteristics (size distribution, morphology, degree of agglomeration, ...)
- consolidation process: grinding process - granulation - densification
3. Shaping procedures
4. Microstructural aspects
- sintering: sintering during solid phase (growth phenomenon) - sintering during liquid phase ("moulding" effect)
- fusion
5. The influence of microstructure on the physical properties - concepts of characterisation (morphology, grain size, density, porosity, ...)
- macro- and micro-cracking phenomena
- mechanical properties
- thermal properties: thermal expansion co-efficient - thermal conductivity
6. Structural ceramics
- oxides, carbides, nitrides, ...
7. Functional ceramics
- ferroelectrics, piezoelectrics, magnetics, super-conductors, ... |
|
| Course objective : | The aim of this course, "Advanced ceramic materials", is to use general concepts to give students an insight into research programmes in the development of new ceramic materials (and/or composites), whether structural or functional. Recent examples of the development of a particular type of material, designed for a particular purpose, will be presented and discussed during the course. These examples are mostly taken from the "Materials Research Bulletin", the monthly journal published by the Materials Research Society. |
|
| Prerequisites : | This course is principally designed for students undertaking a 2nd degree in Chemical Sciences and graduate students enrolled in the DEA Sciences programme. There are, therefore, no prerequisites. |
|
| Organization : | The course takes place according to the availability of the enrolled students. 10 sessions of 1¿ hours are planned (including a short presentation by the students on the subject of their degree or DEA dissertation). |
|
| Written notes : | A copy of the overheads used during the class will be distributed to enrolled students. |
|
| Assessment : | The exam consists of a discussion with the lecturer during an interview at a time to be fixed in line with student's wishes. The exam is planned for the end of the academic year. |
