  1. Polymorphism Or What shape do you want to be?

  2. 2.32 2.26 2.93 4.28 2.65

  3. Some words to remember • Entropy • Molar Volume • What is the relationship between P and T with respect to entropy and volume

  4. Clapeyron Equation • dP/dT= ΔS/ΔV

  5. Types of Polymorphism • Displacive • Reconstructive • Order-Disorder

  6. Displacive • When bonds are slightly kinked • A good example is Low to High Quartz • Usually reversible

  7. Reconstructive • Requires breaking of bonds Graphite Diamond

  8. Order-Disorder • Involves redistribution of cations or anions in a specific site • Example: sanidine, microcline, orthoclase • Use CD open below

  9. Aluminosilicates
