Granules are small, compact particles that can vary in size and composition. They are commonly found in various materials, including soil, sugar, and pharmaceuticals. Granules can be formed through processes like crystallization or granulation, where smaller particles are agglomerated into larger ones. Their size and shape can influence how they behave in different applications, such as in agriculture or food production. In the context of pharmaceuticals, granules are often used to improve the flow and compressibility of powders, making them easier to handle and process. They can also enhance the release of active ingredients in medications. Overall, granules play a crucial role in many industries due to their unique properties.
