Beschreibung
Zusammenfassung:	An abrasive article, comprising a polycrystalline material comprising abrasive grains and a filler material having an average negative coefficient of thermal expansion (CTE) within a range of temperatures between about 70 K to about 1500 K. A method of forming an abrasive article, comprising preparing an abrasive material, preparing a filler material having an average negative coefficient of thermal expansion (CTE) within a range of temperatures between about 150 K to about 1500 K, and forming a polycrystalline material comprising grains of the abrasive material and the filler material.
