When a material (sample) is irradiated with a parallel beam of
dimensional diffraction grating causing the X-ray beam to be diffracted to
intensities of the diffracted beam, provides several information about the
- Angles are used to calculate the interplanar atomic spacings (d-
spacings). Because every crystalline material will give a characteristic
diffraction pattern and can act as a unique ‘fingerprint', the position (d)
and intensity (I) information are used to identify the type of material by
comparing them with patterns for over 80,000 data entries in the
International Powder Diffraction File (PDF) database, complied by the
Joint Committee for Powder Diffraction Standards (JCPDS). By this
method, identification of any crystalline compounds, even in a complex
sample, can be made. - The position (d) of diffracted peaks also provides information about
how the atoms are arranged within the crystalline compound (unit cell
size or lattice parameter). The intensity information is used to assess
the type and nature of atoms. Determination of lattice parameter helps
understand extent of solid solution (complete or partial substitution of
one element for another, as in some alloys) in a sample. - Width of the diffracted peaks is used to determine crystallite size and
micro-strain in the sample. - The ‘d' and ‘I' from a phase can also be used to quantitatively estimate
the amount of that phase in a multi-component mixture.

OPTION 2: SEMI-QUANTITATIVE XRD ANALYSIS All minerals identified by X-ray diffraction analysis will be reported and grouped into major (30%), moderate (10-30%), minor (2-10%) and trace (XRD analysis will be reconciled with a whole. Quantitative X‐ray diffraction (XRD) methods utilizing the adiabatic principles of XRD analysis of mixtures were used to study the formation of ZnAl 2 O 4 quantitatively. Quantitative XRD analysis of blended cements. X-ray diffraction in combination with Rietveld analysis allows a quantification of complex materials like blended. Dauphin fish.
