Abstract: 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:uM.sub.1 .multidot.vM.sub.2 .multidot.wHal.multidot.xChal.multidot.zPhwhere:M.sub.1 =pure metal or mixture of alkali metal, alkaline earth metal and/or AlM.sub.

Abstract: An abrasive disk comprising abrasive grains such as corundum, a bonding material, for example a resin, and a filler material. At least part of the filler material is active in the grinding process.Particles of this filler material are provided in the disk in the form of pellets or granules. The pellets and granules preferably consist of more than one substance. One substance forms a matrix and at least one other substance is imbedded in said matrix.
