Objectives To obtain a knowledge of the fabrication methods, property measurements, sintering and microstructure of a range of engineering ceramics and an understanding of how these factors affect the mechanical, physical and electrical properties of the materials. An understanding of the general problems and solutions which are encountered when designing with brittle materials.
Synopsis Introduction to advanced ceramics (properties, niche markets, comparison with metals, future directions and prospects). Property measurements (strength, toughness, reliability). Sintering and microstructure. Alumina ceramics. Zirconia based ceramics. Non-oxide ceramics, composites. Introduction to functional ceramics (classes, economic significance). Ceramics used as capacitors, piezoelectrics, thermistors and varistors. Optical fibres. Superconductors. Diamond coatings. Ceramic gas sensors. General principles of the problems and solutions used in designing with brittle materials. This includes the identification of critical material properties for a given article, the selection of an appropriate ceramic material that has these properties, the selection of an appropriate fabrication method(s), estimation of the reliability of the component in service, quality control and test methods to be used, costing of the process etc.
