Iron-based corrosion products (e.g., rust) are perhaps the most common type of corrosion products analyzed. The mortar and pestle can be made out of a variety of materials such as agate, corundum, or mullite. In addition, powder XRD can also distinguish between polymorphic phases with the same chemical composition.įor example, calcium carbonate (CaCO₃), a common scale product, is mainly found in the form of calcite however, it is also found as other polymorphs, such as aragonite or vaterite, depending on the environmental conditions present during formation. Usually powdered XRD samples are prepared by hand grinding using a mortar and pestle. While chemical analysis methods can be used to determine elemental composition, they cannot identify what phases are present in scale and corrosion products. their relative concentrations in mixtures based on the diffraction pattern analysis recorded from the powder samples. Powder x-ray diffraction (XRD) is a powerful technique that allows rapid identification of scale and corrosion products. Furthermore, both scale and corrosion products can result in blockages, necessitating costly downtime and repairs. CQDs are both amorphous and crystalline in nature which can be confirmed by XRD results this may depend on the synthesis procedure. XRD works by irradiating a material with incident X-rays and then measuring the intensities and scattering angles of the X-rays that leave the material 1. XRD is an efficient analytical approach for determining material’s crystal structure, unit cell size, crystal spacing, and phase identification. Corrosion reduces structural integrity and can ultimately lead to part failure. X-ray diffraction analysis (XRD) is a technique used in materials science to determine the crystallographic structure of a material.
