Which of the following is considered a Critical Quality Attribute (CQA) for powdered and granule products?
|
Particle size. |
|
https://www.sciencedirect.com/science/article/abs/pii/S0939641112002421#:~:text=Compared%20with%20powders%2C%20granules%20flow%20better%2C%20produce,porosity%2C%20particle%20size%2C%20and%20residual%20moisture%20content.
|
Compared with powders, granules flow better, produce less dust, have a higher density, and segregate less. A number of quality attributes can therefore be defined for granules such as flow properties, mechanical durability, porosity, particle size, and residual moisture content.
