X-ray Microtomography studies of a meteorite sample using the Zeiss Xradia 620 Versa.

Spruce wood scanned with x-ray microtomography. Analysis of cell wall thickness.Field-of-view (diameter, height): 1.0 mm, Spatial resolution (voxel size) : 1.0 μm.

Studies of granular compaction using Zeiss Xradia 620 Versa and the Deben CT5000TEC in-situ load stage.

WOOD PELLET (FOR HEATING)

Scanning och 3D bildanalys av en träpellet (för uppvärmning). Provets diameter är 8.0 mm, och rumsupplösningen är 4.0 mikrometer. Den öppna porositeten inuti provet visas här i blått. Projektet är ett samarbete med RISE, Research Institutes of Sweden.

Tegel

3D-studie av slagginträngling i tegel från ett av LKAB:s pelletsverk. Provets storlek är ca 12x14x16 mm (B,D,H), och upplösningen är 21 mikrometer.

3D X-ray microtomography

X-ray microtomography (XMT, XCT, MicroCT) is a non-destructive technique for 3D imaging and characterization of materials, including minerals, rocks, metals, composites and wood, with sub-micron resolution. From the acquired 3D data it is possible to make quantitative analysis of internal features such as porosity, cracks, grains, fibers etc., as well as determine material deformation and strain.

XMT is a non-destructive technique that do not require any sample preparation. The sample is placed in the system and the scan is started. The result describes the 3D microstructure of the material, based on its density. After a scan, the same sample can be tested using other complimentary techniques (such as SEM), or scanned repeatedly during in-situ loading using XMT.
