Particle density (packed density) - Wikipedia

The particle density or true density of a particulate solid or powder, is the density of the particles that make up the powder, in contrast to the bulk density, which measures the average density of a large volume of the powder in a specific medium (usually air).Density and Porosity | Micromeritics Pharmaceutical,True Density: True density is the density of the solid material excluding the volume of any open and closed pores. Depending on the molecular arrangement of the material, the true density can equal the theoretical density of the material and therefore be indicative of how close the material is to a crystalline state or the proportions of a binary mixture.How to measure the true density for nanopowder,2- Tamped or packed density: the weight divided by the total volume occupied by the powder poured in a measuring cylinder and tamped according to standard conditions (there is ASTM in this regard). 3- The true density: the weight divided by the true volume of the powder (the voids between the particles are NOT included), the true volume can
