X-Ray and Material Testing

X-Ray and Material Testing

The XRD and Material Testing facilities use complementary techniques to determine the physical, crystalline and chemical properties of the different types of materials. X-ray diffraction (XRD) is a technique used in materials science and crystallography to determine the atomic and molecular structure of the materials.

Thermogravimetric analysis (TGA) is used to measure changes in the weight of a sample as a function of temperature while the sample is subjected to a controlled temperature program in a controlled atmosphere. It is commonly used to characterize the thermal stability, composition, and decomposition kinetics of materials. Nitrogen adsorption-desorption isotherms at -196 °C are used to characterize the porosity and surface area of materials. ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy) is used to determine the elemental composition of materials. UV accelerated weathering tester is used to simulate the effects of sunlight exposure on materials. These chambers are designed to subject samples to controlled levels of ultraviolet (UV) radiation, temperature, and humidity, replicating the conditions that materials experience when exposed to outdoor environments over extended periods. Salt spray testing is a standardized method used to evaluate the corrosion resistance of materials and coatings.

  • XRD X’Pert PRO

    Powder or Thin Film X-ray diffraction – an analytical technique used for phase identification and quantification of crystalline materials. It provides information on unit cell structure parameters and crystallographic orientation. Also used for contaminant detection and analysis. Grazing Incidence X-Ray Diffraction can also be done.

    Reciprocal Space Mapping – is used to identify crystallographic orientation, composition, stress, and mismatch of heterostructures.

    X-ray Reflectivity (XRR) – is used to identify film thickness, density, and interface roughness.
