An abrasive article, and methods of making and using same, containing an inorganic metal orthophosphate salt. The abrasive article including a coated abrasive article having a size or supersize coating layer containing an alkali metal or alkaline earth metal orthophosphate salt devoid of hydrogen. The inventive abrasive article reduces the grinding energy required while improving abrading efficiency in some cases.

Abrasive article containing an inorganic metal orthophosphate

Coated abrasive article comprising a backing bearing on at least one major surface thereof erodible agglomerates and abrasive grains, wherein the erodible agglomerates consist essentially of a grinding aid and the erodible agglomerates are in the form of rods. The erodible agglomerates can be between or above or between and above the abrasive grains. The coated abrasive article of this invention utilizes a higher level of grinding aid than coated abrasive articles of the prior art.

Coated abrasive containing erodible agglomerates
