Understanding Particle Size
Micron grade is not the same as D50
Micron grade
The nominal fineness used to name a product – usually a top cut or sieve pass. It is not the same as D50.
D50
The median particle size: half of the particles by volume are finer than this value.
D90
90% of the particles are finer than this value.
D97
97% of the particles are finer than this value – often used as the practical top cut.
All D50, D90, D97 and chemical values are published only after approval by our laboratory. Grades below 5 µm are listed for reference and their availability must be confirmed.
