Bulk Density

Bulk density is the mass per unit volume of a loose powder bed. The unit volume includes the spaces between the particles, and the envelope volumes of the particles themselves. The method used to fill the material into that volume can affect the degree to which the powder is compressed and can thus influence the bulk density value. 14,15 Bulk density can be calculated using Eq.
