An abrasive article with abrasive grain such as corundum, a binder which is a hardenable organic or inorganic system, for example plastic, such as phenol resin, and grinding-active fillers, as well as an abrasive with abrasive grain such as corundum, a binder which is a hardenable organic or inorganic system, for example plastic, such as phenol resin, and grinding-active fillers. The abrasive compound of the abrasive consisting of abrasive grain, binder and the fillers is placed on a flexible substrate, which is formed by a nonwoven fabric. New low-priced fillers with low toxicity are incorporated in the abrasive article and, in fact, metal complex salts with the following structure: uM1xvM2xwHalxxChalxzPh where: M1=pure metal or mixture of alkali metal, alkaline earth metal and/or Al M2=pure metal or mixture of Zn, Mn, Fe except for Fe as chloride Hal=pure halogen or mixture of F, Cl, Br, I Chal=chalcogenides, O and/or S Ph=phosphate or more highly condensed phosphates PrOs(r=1 to 10, preferably 1 to 2, s=4 to 20, preferably 4 to 7) u, v, w, x or z=0 to 95%, and the total of u and v=1 to 95%, preferably 20 to 80%, and the total of w, x and z=1 to 95%, preferably 20 to 80%, and that the total of u, v, w, x and z is 100%. These fillers are melted or sintered with each other.
