Particle Shape

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 morphology analysis is very important throughout
this process. Bettersize particle image analyzer is well-known for its using of
particle shape analysis.

Particle shape, also named as particle morphology, is currently characterized
by measuring and calculating the projected shapes of the particles, including
outline contour and roughness. All historical methods employ microscopic
imaging systems as the basis of performing an image analysis. In the particle
shape analysis, the characterization of irregular shaped particles is common,
with important features including particle roundness, the aspect ratio of
elongated (or fibrous) particles, and the ratio of thickness-to-diameter for
flakes or platelets, etc. The images are taken by microscope and then analyzed
by software. The specific analysis methods are:
(1) Roundness: it can be calculated by the circumference of the circle equal to
the particle area divided by the actual circumference of the particle (could
also be calculated by "the equivalent diameter of the circumference is divided
by the area equivalent diameter"). But no matter what algorithm is used , the
closer the value is to 1, the better the roundness of the particles.
(2) Aspect ratio: This is the ratio of the length of the particle circumscribed
rectangle to the average width of the particle.
(3) Diameter-thickness ratio: the ratio of the diameter of the particle-
equivalent circle to the thickness of the particles.
