Introduction 

 

Particle shape is currently characterized by measuring and calculating the projected shapes of the particles, including outline contour and the whole projection pattern. The shape of particles can impact many properties, including specific surface area, flowability, magnetic property, packing property, abrasiveness, and chemical activity. To improve product performance, particle shape is a key factor that should be considered in synthesis, and formulation development. Therefore, particle shape analysis is very important throughout the industrial and scientific research of powders, emulsions, and other particle products.

Bettersize particle image analyzers are well-known for providing particle form analysis, which reflects the geometrical proportions of a particle. For example:

 

(1) Circularity (Roundness): The circularity 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 perimeter equivalent diameter 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) L/W ratio: This is the ratio of the length (L) of the particle circumscribed rectangle to the average width (W) of the particle.


(3) Aspect ratio: The ratio of the maximum Feret diameter to the minimum Feret diameter.

 

Bettersize image analyzers provides 24 parameters in total to describe the size and shape of particles. A detailed description of those particle size and shape parameters can be found HERE.
