Q

Properties of Ceramics

A
  1. Hardness (resist abrasion, wear)
  2. Chemical Inertness ( resist corrosion and chem react)
  3. High compressive strength (withstand pressure)
  4. Heat resistance (have thermal stability)
  5. Low thermal conductivity (poor conductors of heat)
  6. Electrical insulation (don’t conduct electricity)
  7. Dimensional stability (minimal dimensional changes)
