摘要： A method of making conglomerate abrasive particles includes: providing agglomerate abrasive particles comprising mineral particles in a first vitreous binder; combining the agglomerate abrasive particles with a second vitreous binder material precursor to form precursor conglomerate abrasive particles; and heating the precursor conglomerate abrasive particles to convert the second vitreous binder material precursor into a second vitreous binder, different from the first vitreous binder, thereby forming the conglomerate abrasive particles. The first vitreous binder differs from the second vitreous binder by at least one of: i) elemental composition, or ii) an intrinsic physical property; and wherein the conglomerate abrasive particles can pass through a testing sieve having one-millimeter openings. Conglomerate abrasive particles preparable by the method, and abrasive articles containing them, are also disclosed.

摘要： An abrasive rotary tool includes a tool shank defining an axis of rotation for the rotary tool, and an abrasive external working surface. The abrasive external working surface includes a resin, and a plurality of porous ceramic abrasive composites dispersed in the resin, the porous ceramic abrasive composites including individual abrasive particles dispersed in a porous ceramic matrix. At least a portion of the porous ceramic matrix comprises glassy ceramic material. A ratio of the average porous ceramic abrasive composite size to the average individual abrasive particle size is no greater than 15 to 1.

摘要： Interrupted structured abrasive articles comprise an abrasive layer comprising shaped abrasive composites that extend outwardly from a first major surface of a backing to which they are secured. The abrasive layer defines at least one open region that is free of the shaped abrasive composites and may extend partially or completely through the backing. In some embodiments, each of the open regions comprises a circular area of at least 1.5 square centimeters, and when combined the open regions have total area that is at least 10 percent of the area of the first major surface of the backing. Interrupted abrasive articles are useful in single-sided polishing processes.
