Theoretical-practical classes (using computer resources).
Laboratory classes (given in the Ceramics and Glass laboratory). These classes may include a theoretical and practical part (for problem solving and case study).
The evaluation consists of 3 evaluation moments: Test1 (40%) + Test2 (40%) + Form with presentation and treatment of data from practical classes and discussion (20%).
The final score being N = 0.4T1 + 0.4T2 + 0.2P
2/3 of the practical work is required
Exam exemption: N greater than or equal to 10
Technical ceramic manufacturing methods - Powder synthesis processes: by solid state reactions; from liquid solutions (precipitation, hydrothermal synthesis, evaporation, atomization, via sol-gel); presence of gas phase (nitridation, chemical vapor deposition, CVD). Powder consolidation and densification methods: isostatic pressing, belt processing, mold injection, hot pressing, isostatic hot pressing (HIP), final finishing, quality control). Glass ceramic processing. Characterization of technical ceramics (microstructural analysis; structure-microstructure-properties relationships; surface analysis).
Advanced ceramics: properties, applications and evaluation of these ceramics: functional ceramics (insulators, substrates, dielectrics, piezoelectric and pyroelectric, ferroelectric, electro-optical, semiconductors, ionic and magnetic conductors); structural ceramics (thermal shock and oxidation resistant, wear resistant, carbon and graphite composite ceramics). Concrete applications of special high-tech ceramics (eg electrical and electronic devices, gas sensors, biomaterials, cutting tools, bearings, gas turbines, nuclear industry).
Laboratory practical classes:
-Synthesis of a ceramic powder by sol-gel method
- Particle size distribution analysis of a ceramic powder by laser diffractometry
- Differential thermal analysis
