An Introduction to Mineral Sciences
Such a pair of vacancies is called a Schottky defect, although the two vacancies
are not necessarily directly associated with each other in any way. In a crystal of
NaCl for example a pair of vacancies such as shown in Figure 7.3 is equivalent to
...

Chemistry Vol (1 and 2)
These are called Schottky defect and Frenkel defect. Schottky Defects : This
defect is generally found in highly ionic compounds such as NaCl and CsCl, with
high coordination number and where the positive & negative ions are of similar
size ...

Competition Science Vision
Examples of this type defect are ZnS, AgCI, AgBr and Agl. Key Points • Schottky
defect appears more often than Frenkel defect. This is due to the fact that the
energy needed for the Schottky defect is much less than that needed to form a ...

Objective Chemistry For Iit Entrance
Photo-sensitivity of AgBr is due to the presence of (a) Schottky defect (b) Frenkel
defect (c) metal excess defect (d) metal deficiency defect 109. If the energy
needed to produce a Schottky defect be x and that needed to produce a Frenkel
defect ...
Three different types of intrinsic point defects have been identified, (i) Schottky
defect (ii) Frenkel defect and (iii) atom interchange defect. Schottky defect is a
vacancy in an otherwise perfect lattice and usually encountered in solids ...

Defect-phase Equilibrium and Ferroelectric Phase Transition ...
In the case of a close packed structure, there should be a much higher
concentration of the Schottky defects. In binary metal oxides, only a full Schottky
defect reactions exist. However, since BaTiO3 is a ternary system, not only the full
Schottky, ...

Electrochemistry of Zirconia Gas Sensors
If an atom leaves its site in the lattice (thereby creating a vacancy) and then
moves to the surface of the crystal, it becomes a Schottky defect. On the other
hand, an atom that vacates its position in the lattice and transfers to an interstitial
position ...

The Pearson Guide to Objective Chemistry for the AIEEE
Which among the following is likely to have Schottky defect? (a) ZnS (b) AgBr (c)
NaCl (d) none of these 27. ZnO is white when cold and yellow when heated. It is
due to the development of (a) metal excess defect (b) Frenkel defect (c) Schottky
...

Metal Oxides: Chemistry and Applications
To form a Schottky defect, ions leave their normal lattice positions and relocate at
the crystal surface, preserving overall charge neutrality. Hence, for a metal
monoxide, MO. vacant sites must occur equally in the cation and anion sublattice
and ...

Textbook of Physical Chemistry
These are due to imperfect packing during the original crystallization or they may
arise from thermal vibrations of atoms at elevated temperatures due to excitation
of atoms. Common point defects are: 1. Schottky defect and 2. Frenkel defect ...

Size effect and vacancies in nanomaterials
Vacancies (also called Schottky defect) play a major role in the electrical and thermal transport as well as the mechanical behavior of materials. A vacancy is the ... «Nanowerk LLC, gen 11»
