forming a glass matrix. The feldspars are mixtures of potassium alumino-silicate (K 2 O Al 2 O 3 6SiO 2) and sodium alumino-silicate which was confirmed in the present study. This was explained by the reaction of P with fuel ash elements instead of the bed particles.The single-scattering properties of Gaussian random spheres are calculated using the discrete dipole approximation. The ensemble of model particles is assumed to be representative for a feldspar dust sample that is characteristic for weakly absorbing irregularly shaped mineral aerosol. The morphology of Gaussian random spheres is modeled based on a statistical …Detrital feldspars,

few studies have focused on the layer characteristics of K-feldspar bed particles. The layer characteristics of K-feldspar bed particles were therefore investigated by collecting bed material samples of different ages from fluidized bed combustion of woody fuels in large-scale bubbling …Note that we have only presented a few examples. Bulk density is a measure of how well particles pack together in a defined volinne. It depends on the shape of the particles comprising the powder. Most of the organic compounds (pharmaceuticals) will exhibit elongated shaped particles. Note that at least 50% of the voliunes presented in 4.1.12 are. in most cases,
