| Angle of Repose | When powder is dropped, it accumulates. This is the angle of the ridge of the pile. |
|---|---|
| Collapse angle | The angle of repose is the angle of the ridge of the pile after it is crushed by impacting it after measurement. |
| Difference Angle | It is the difference between the angle of repose and the angle of collapse. |
| Agglutination | When powder is placed on the top of a three-tier sieve (each with a different mesh size) and sieved for a specified time at a specified vibration intensity, some powder will form clumps due to the vibration. This value is obtained by calculating the mass of these clumps using a specified method. For relatively large powders that do not form clumps, uniformity is used instead of cohesion. |
| Uniformity | This is the ratio of the size that corresponds to the cumulative 60% of the particle size distribution to the size that corresponds to the cumulative 10%. Depending on the particle size, the degree of agglomeration may be used instead of this value. |
| Spatula angle | It is measured using a metal plate called a spatula placed in the powder bed. When the powder bed is dropped, it is the angle of the peak formed by the powder remaining on the spatula. |
| Loose bulk density | Powder is dropped into a container, filled until it overflows, and then leveled off to determine the mass per volume. |
| Packed bulk density | This is the mass per volume after a container filled with powder is leveled off when it is tapped to a specified height, a specified number of times per unit time, and for a specified period of time. As the volume decreases due to tapping, more powder is added. |
