X-Ray diffraction (XRD)
X-ray diffraction (XRD) is a non-destructive important tool used to identify phases by comparison with data from known structures, quantify changes in the cell parameters, orientation, crystallite size and other structural parameters of single crystalline or polycrystalline material. Most research labs and technology companies lack the scientific infrastructure and know-how to personally perform X-ray measurements. Our center personnel experienced with extensive number of materials, is at your service to help you solve your problem which is performed quickly and smoothly (usually on the same day).
This is the technique used for investigating solid samples. It’s mainly used with samples in form of single crystals and powders. Powder sample preparation can be accomplished with our crushing equipment. Typical use is execution of qualitative analysis: phase identification in polycrystalline samples, identification of minerals in geological samples, in industrial ceramics, refractories, cements, mortars. The technique is suitable for the quantification of non-crystalline component (amorphous) as well.
Texture analysis: the reconstruction of the distribution of orientation of the crystallites in polycrystalline samples allows for the reconstruction of the sample microstructure. Specific orientation of crystallites develops as a result of industrial production processes (as for many metallic parts) or by action of external or internal agents.
These measurements are vital not only for scientists working with bulk, but with nano-materials as well.
The X-ray laboratory in the department of physics is equipped with a Bruker (D8 advance eco) diffractometer (Cu radiation) use Bragg-Brentano geometry for unparalleled powder diffraction. The D8 ADVANCE Eco is the full-sized goniometer class powder XRD under ambient conditions. Like no other system the D8 ADVANCE Eco pairs excellent analytical performance for phase identification of the samples, single phase or multiphase, organic or inorganic, is performed by matching the sample's X-ray diffraction spectrum against International Center for Diffraction Data (ICDD) of diffraction patterns.
The lab supports the basic and applicative work of departmental scientists, and other Israeli researchers. At the same time, it maintains intensive collaboration with industrial partners who are satisfied by the lab’s ability to perform the XRD measurements needed to characterize materials.
