The properties of particles include particle size, shape, surface structure and pore structure. The shape of the particles can impact on many properties of a powder sample, including specific surface area, flowability, magnetic property, packing property, abrasive property and chemical activity. In order to improve the characteristics and performance of some products, particle shapes have been designed and produced based on their applications by industrial and scientific research. Therefore, particle shape analysis
is very important throughout this process. Bettersize particle image analyzer is well-known for its using of particle shape analysis.
