摘要

GLASS SPANISH HAVING IMPROVED GRAIN SIZE DISTRIBUTION AND A PROCESS FOR THE PRODUCTION OF THIS. The invention relates to a glass powder containing as its main component ground glass dust particles having a ground glass dust particle size having an average particle size of 1.5 µm, and which is free of particles having a particle size of 10 ≤10 m, and which is free of particles having a particle size of 10 ≤ m and also to such a production process. Glass powder is thus particularly suitable as a filler of plastic dental compositions, in particular dental composites.
