Feldspar: a filler with a high degree of chemical resistance
With a proportion of almost 60 % by weight of the structure of the earth’s crust that is accessible for us, feldspars are by far the most frequent group of minerals. Feldspar is a chemically resistant framework silicate with a thick-slated grain morphology. In our production facilities mainly potash feldspars are processed and separated by an elaborate screening technique, then classified and micro-ground.
