Ceramics and Glasses Ceramics page 2 Definition of Ceramics Ceramics / Glasses – Structure page 3 Chemistry Crystalline Structure Ceramics / Glasses – Composition page 4 Ceramic Composition Glass Composition Ceramics / Glasses Properties page 5 Very brittle High melting temperatures Durable High chemical stability Low electrical and thermal conductivity Pores? Flaws? Cracks? page 6 In ceramics and glasses, a decrease in the flaws, cracks and pores will result in: Why are ceramics brittle? page 7 Inherent flaws/cracks/pores Directional bonding Large & complex Burgers vectors Restricted slip systems Ceramics / Glasses Properties page 8 High strength Stronger in compression than tension High hardness Fine grain ceramics are stronger than coarse grain ceramics The problem with ceramics is their lack of ductility, not their lack of strength Ceramics / Glasses Applications page 9 List of Ceramics and Glasses Applications Ceramics Processing Techniques page 10-11 Ceramics & glasses are difficult to fabricate and process
