Features/Benefits
PW 325™ is crushed, milled and screened to maintain a top side of 325 US Mesh. Liberated magnetic and paramagnetic minerals are removed with rare-earth roll magnets to maintain a consistent iron content below 80 ppm. The precise control of particle size distribution and chemistry improves production processes, allowing better control of production costs and compliance with customers’ chemistry demands.
Because of its reliable chemical composition and consistent gradation quality, PW 325™ is an excellent choice for a variety of applications requiring high-purity silica.
