However, when we are talking about density of powders, bulk density is no longer a meaningful value, because even if the mass of the material is constant, the volume that the powder occupies can vary widely depending on how the powder is packed. The mass of the particles divided by the volume they occupy that includes the space between the particles (ASTM D5004). Poured bulk density is determined by pouring a sample of known mass into a .61 g/cc in two size ranges, small (380–550 μm) and large (700–1200 μm) (stereoscope/image analysis), were .
