“…The 3D size, morphology, internal porosity, and the position of a given particle in the granular assembly are types of information that are available from a single scan ( Figure 2 ). Due to the non-destructive nature of X-ray CT imaging, repeated scans of the same sample after an intervention such as loading [ 11 , 16 , 49 , 56 ] or heating [ 3 ] are possible and allow for time-lapse (4D) studies of changes in the assembly [ 53 ]. The digital data, collected with each scan, can feed directly into computed models about the particles and their behaviour in the granular assembly [ 27 , 47 , 48 , 54 ].…”

“…X-ray tomography has been used to study geological material, mainly quartz-rich sand [ 9 , 11 , 13 , 18 , 49 , 50 , 56 ], but also ores and coal [ 4 , 7 , 25 , 38 , 48 ]. A field of interest is the behaviour of sand particles during deformation [ 11 , 13 , 36 , 49 , 53 , 56 ]. Other studies have been concerned with the development of image processing methods to aid with the identification, description, and tracking of particles during deformation [ 6 , 44 ], and often use a specific reference material, such as Caicos ooids [ 36 ], ceramic proppant [ 39 ], or industrially-made zeolite particles [ 44 ].…”

A Review of Particle Size Analysis with X-ray CT

Particle size and morphology analysis is a problem common to a wide range of applications, including additive manufacturing, geological and agricultural materials’ characterisation, food manufacturing and pharmaceuticals. Here, we review the use of microfocus X-ray computed tomography (X-ray CT) for particle analysis. We give an overview of different sample preparation methods, image processing protocols, the morphology parameters that can be determined, and types of materials that are suitable for analysis of particle sizes using X-ray CT. The main conclusion is that size and shape parameters can be determined for particles larger than approximately 2 to 3 μm, given adequate resolution of the X-ray CT setup. Particles composed of high atomic number materials (Z > 40) require careful sample preparation to ensure X-ray transmission. Problems occur when particles with a broad range of sizes are closely packed together, or when particles are fused (sintered or cemented). The use of X-ray CT for particle size analysis promises to become increasingly widespread, offering measurements of size, shape, and porosity of large numbers of particles within one X-ray CT scan.
