Abstract: An agglomerate abrasive grain includes a mixture of individual abrasive grains and hollow bodies, wherein the abrasive grains and the hollow bodies are held together via a binding matrix of aluminosilicate and alkali silicate, and the agglomerate abrasive grain has an open porosity and a closed porosity in each case ranging from 5% by volume to 40% by volume, wherein the total porosity of the agglomerate abrasive grain is less than 50% by volume.
