Ceramics and Glasses

Ceramics and Glasses

1. Ceramics

   • bonding either covalent or ionic
   • whitewares
     • table wear
     • electrical insulators
   • structural ceramics
     • cement
     • concrete
     • bricks
   • refractories
     • withstand high temperatures
     • furnace linings
   • technical ceramics
     • cutting tools
     • dies

2. general charcteristics

   • low electrical and thermal conductivity
   • high strength in compression and hardness
   • brittle
   • good temperature and corrosion resitant
   • good wear resistant

3. Glass

   • optical properties
   • formed by cooling rapidly to prevent crystals

4. glass ceramics

   • higher strngth
   • excellent thermal shock resistance
