IMPORTANCE OF SIZE CONTROL AND ANALYSIS

Particle size distribution is an important aspect to consider in using an abrasive or functional filler. Size control in the sub-micron range requires sophisticated processing techniques. It has become increasingly important as finer and more precisely sized particles are required. Accurate size analysis is also critical to ensure that products meet established specifications.
