Why is XRD Important?
It’s useful for studying Crystal structure
This method have the details about
-
Grain size (or) Crystal size
-
Orientation of the crystal
-
Cold worked, Distorted and Internally stressed crystals
-
Re-Crystallization
-
Preferred orientation etc
Methods of Examining and Measuring the condition of Crystal Structure
-
The Laue back reflection method
-
The Rotating Crystal method
-
The DeBye- Scherrer (or) Powder method:
The Laue back Reflection method:
It’s applicable to single crystals (or) poly-Crystalline masses.
When a beam of Mono chromatic (i.e. of Single Wavelength) X-Ray is directed as a narrow pencil at a specimen of a metal diffraction takes place at certain of the crystallographic planes.
The Rotating Crystal method:
It’s a useful method for determining angles and positions of planes.
Crystallographic planes are brought in to reflecting positions by rotating a crystal (Specimen) about one of it’s axis while simultaneously radially it with a beam of mono chromatic x-Rays.
If crystal orientation planes are known, the angles and directions can be calculated.
The DeBye- Scherrer (or) Powder method:
The narrow pencil of monochromatic X-Rays is diffracted from the powder and recorded by the photographic film as a series of lines of varying armature.
By the Bragg Equation:
nλ=2d Sinθ
Where,
λ– Wave length of X-ray
d- Spacing of the atomic planes
θ – Angle of reflection
