Particle size analysis resistance method
1 Scope
This standard specifies the resistance measurement is dispersed in an electrolyte solution of particle size distribution method. This method is suitable for measuring pulse by
Correlation between pulse height and the particle diameter and particle volume or to obtain a particle size distribution, the measurement range of about 0.4μm ~ 1200μm.
Although this standard does not propose specific materials requires measurement details, but gives a porous material such as a metal powder and a conductive material
The particle size analysis guidelines.
