Average Particle Size (Microns) - AVPS

This test procedure was employed in the Foresight Ceramic Database and now is available for those having an account at Insight-Live.com. Accumulating test data using the variables defined in these procedures enables us to create tools that enable you to compare the physical properties of materials and recipes.


Particle size analysis falls into two categories: Ultimate and physical. Physical particles are those we can measure using ordinary sieves. Ultimate particles, in the micron range, require the use of specialized devices.


VAL - Value (V)

The size in microns of the average particle of a powder sample

    Processed ceramic materials are typically ground to 200 mesh and feel very fine to the touch. With some you can detect some particle grains between your fingers. The amount of these "physical particles" can be measured by washing or shaking the ceramic powder through a sieve. Using water washing and...
