Powder processing is a field of materials science and engineering focused on the methods and principles for handling, modifying, and consolidating particulate materials to produce components or bulk materials. It investigates the physical and chemical properties of powders, particle interactions, and the effects of processing parameters on the final material's structure and properties. Key characteristics include techniques such as mixing, granulation, compaction, and thermal treatment (e.g., sintering), enabling the fabrication of complex shapes and materials with tailored microstructures for diverse applications.
