Frequently Asked Questions

It evaluates the sedimentation of particles in suspension, particularly centrifugal photo-sedimentation, to study the size distribution of alumina powders and similar powders based on them.

The procedure considers particles in the 0.1 to 20 μm range, with a median particle size of 0.5 to 5.0μm.

This helps maintain quality control, product specification, and material research by assuring the accuracy of the particle size measurements.

Particle size distribution affects packing density, sintering behavior, flowability, and final product quality, making it a critical parameter in manufacturing and material performance.

The law of strokes is applied to determine the resistance to movement, the speed at which particles move, and their arrangement during the given manipulations.
