2. Crystallography and elements of crystal
Introduction:
• Crystallography:
• Crystal:
• Crystallization
• Elements of crystals:

3. Crystallography:
• Crystallography Is a
branch of mineralogy
which deals with the
study of crystals, their
internal structure and
external shape.

4. Crystal:
• A Crystal may be
defined as a nature
solid body bounded
by smooth and plain
surfaces, arranged in
orderly pattern,
which is an outward
expression of a
regular internal
atomic structure.

5. Square prism
crystal
Hexagonal prism
crystal

6. Crystallization
• Crystallization may be define as the
crystals are formed by the solidification of
minerals from the gaseous or liquid states
or from solutions, under controlled
conditions of temperature and pressure.

7. Elements of crystals
• There are nine elements of crystal
1. Crystal faces
2. Crystal Edge
3. Solid angle
4. Interfacial angle
5. Distortion
6. Simple form and combination

8. 7. Zone and zone axis
8. Crystallographic axis
9.Symmetry
• Plane of symmetry
• Axis of symmetry
• Centre of symmetry
