The meaning of particle shape

May. 22, 2024

The properties of particles include particle size, shape, surface structure and pore structure. The shape of particles affects many properties of powders, such as specific surface area, fluidity, magnetism, filling, grindability and chemical activity. In order to highlight the excellent characteristics of some products, the industrial and scientific research fields carry out particle shape design for the functions of powder products to improve product quality and performance. Here are the effects of particle shape on

product performance:

Numer	Product category examples	Quality requirements	Shape that meets the requirements
1	Paint, Ink, Cosmetics	Strong fixing power and good reflective effect	Flake Particles
2	Rubber filler	Reinforcement and wear resistance	Granular Particles
3	Plastic filler	Improve impact strength	Long particles
4	Explosivesand detonators	Stability	Smooth spherical particles
5	Washing powder	Solubility	Aggregated particles
6	Food, lithium battery materials, tin-lead alloy powder, etc.	Fluidity	Spherical particles
7	Abrasive	Grinding type	Polygonal particles
