Powder Density | Tapped Density / Powder Bulk Density
The bulk density, the tapped (or tap) density and the Hausner ratio measurement is very popular for powder characterization because of both the simplicity and the rapidity of the measurement. Moreover, the density and the ability of a powder to increase its density are important parameters for storage, transportation, caking, etc.

Recently these two-dimensional attenuation signals have been extended to three-dimensional density distribution by the technique of computed tomography (CT). Beside the classic X-ray attenuation signal dominated by photoelectric effect, Compton effect and Rayleigh stering, X-ray diffraction resulting in the crystalline structure of the 4H-SiC superimposes the reconstructed result.
