Temperature can have a strong impact on the behaviour of powders. At elevated temperatures the powders can become sticky or exhibit partial melting resulting in a decreased or increased flowability. Additionally, at sub-zero temperatures freezing can occur which also will impede flowability.
These changes will affect the behaviour in a consolidated state, and influence for example the flowability, cohesion or angle of internal friction. However, it also influences fluidized powders and can change their behaviour e.g. regarding their air-retention.
