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

    1. The Laue back reflection method
    2. The Rotating Crystal method
    3. 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


λ– Wave length of X-ray

d- Spacing of the atomic planes

θ – Angle of reflection

  1. I really like it when individuals arrive collectively and share opinions, fantastic website, preserve it up.

  2. Your fashion is so distinctive when compared with several others. Thanks for publishing once you possess the chance,Guess I’ll just make this bookmarked.two

  3. That is a subject shut to my heart cheers, in which are your get in touch with specifics however?
