A quick way of deciding if a clay is coarser or finer than another. The is the micron size when 50% of the clay is finer and 50% is coarser.
|Tests||Average Particle Size (Microns)|
|Tests||% < 10 microns|
Utlimate particles of ceramic materials are finer than can be measured even on a 325 mesh screen. These particles are the key players in the physical presence of the material.
Tests conducted to determine particle populations, sizes, shapes, densities, surface areas, etc.
