Question

State True' or 'False', fill in the blanks, or draw 1. Frenkel defects are point defects. 2. Schottky defects are equilibrium defects 3. Vacancies are point defects in ionic crystals 4. Interstitial defects are line defects. 5. Substitutional defects are point defects 6. Frenkel defects are not thermodynamically equilibrium defects 7. Mathematically, point defects are zero-dimensional defects. 8. Mathematically, dislocations are line defects. 9. An incomplete plane in a crystal creates an edge dislocation 10. Draw a Burger's circuit and Burger vector around a negative edge dislocation 1 pt 1 pt 1 pt 1 pt 1 pt 2 pt 1 pt 1 pt 1 pt in a simple cubic crystal. 5 pt

Explanation / Answer

1. True

The Frenkel defect forms when an atom or smaller ion (usually cation) leaves its place in the lattice, creating a vacancy, and becomes an interstitial by lodging in a nearby location

2. True

a Schottky defect will always result a crystal structure in equilibrium.
