Question

7. Which do you think will have a larger impact on the density of a ceramic - a Frenkel or Schottky defect. Why?.....(2 points)

Answer 1

Schottkey defect have a larger impact on the density of the ceramic becauseIn Schottky defect, both cation and anion leave the solid crystal. In Frenkel defect, only the smaller ion (cation) leaves its original lattice site; whereas, the anion remains in original lattice sites. One Schottky defect leads to the formation of two vacancies, whereas one frenkel defect leads to the formation of only one vacancy that's why the density is highly impacted in Schottky defect.

Please dear thumpsup for the answer. Thank you.
