Why almost every crystal system has peak around 32 degree (2 theta) ?

The XRD peak position near 32 degrees indicates the presence of a specific crystalline structure in the sample being analyzed. This position corresponds to a specific angle at which X-rays are diffracted by the crystal lattice, providing information about the arrangement of atoms in the material.
The XRD peak position can be influenced by several factors, including the type of crystal structure, the orientation of the crystal lattice, and the size and shape of the crystals in the sample. Other factors such as temperature, pressure, and impurities in the sample can also affect the peak position.
The XRD peak position is measured using a technique called X-ray diffraction, which involves directing a beam of X-rays at the sample and measuring the angles at which the rays are diffracted. These measurements are then used to calculate the peak position and intensity, which can provide information about the crystal structure and composition of the sample.
Yes, the XRD peak position can be used as a fingerprint to identify different crystalline structures and determine the composition of unknown samples. By comparing the peak position and intensity to known reference patterns, scientists can identify the type of crystal structure present in the sample.
The XRD peak position is a powerful tool in materials research, as it can provide information about crystal structure, phase composition, and microstructure of materials. By analyzing the peak position and intensity, scientists can gain insight into the properties and behavior of materials, which can be used to improve their performance or develop new materials with specific properties.
