Abstract: Polycrystalline compacts include a polycrystalline superabrasive material comprising a first plurality of grains of superabrasive material having a first average grain size and a second plurality of grains of superabrasive material having a second average grain size smaller than the first average grain size. The first plurality of grains is dispersed within a substantially continuous matrix of the second plurality of grains. Earth-boring tools may include a body and at least one polycrystalline compact attached thereto. Methods of forming polycrystalline compacts may include coating relatively larger grains of superabrasive material with relatively smaller grains of superabrasive material, forming a green structure comprising the coated grains, and sintering the green structure. Other methods include mixing diamond grains with a catalyst and subjecting the mixture to a pressure greater than about five gigapascals (5.0 GPa) and a temperature greater than about 1,300° C. to form a polycrystalline diamond compact.

Abstract: Polycrystalline diamond constructions are formed from a mixture of diamond grains including a first volume of fine-sized diamond grains, and a second volume of coarse-sized diamond grains. The fine-sized diamond grains are partially graphitized, and the coarse-sized diamond grains are not graphitized. The mixture of diamond grains is subjected to high pressure/high temperature sintering process conditions in the presence of a sintering aid thereby forming polycrystalline diamond. Contact areas between coarse-sized diamond grains in the polycrystalline diamond construction are substantially free of graphite.

Abstract: Systems and methods are directed to selecting unpolished regular-polygonal diamonds; selecting diamond powder based on size, profile and hardness to use as acceleration media; and polishing the regular-polygonal diamonds by accelerating at least the diamond powder using a plurality of spray patterns determined as a function of the respective hardnesses of the diamond powder and the unpolished regular-polygonal diamond, the spray patterns directed at the unpolished regular-polygonal diamonds. The method further includes accelerating the regular-polygonal diamonds and the diamond powder to create the spray patterns; directing the spray patterns so that they overlap causing the diamond powder to polish the regular polygonal diamonds; separating the regular-polygonal diamond from the diamond powder; and repeating the steps of accelerating the regular polygonal diamonds and the diamond powder and the separating until the regular-polygonal diamond is polished.

Abstract: Nano polycrystalline diamond is composed of carbon, an element of different type which is an element other than carbon and is added to be dispersed in carbon at an atomic level, and an inevitable impurity. The polycrystalline diamond has a crystal grain size not greater than 500 nm. The polycrystalline diamond can be fabricated by subjecting graphite in which the element of different type which is an element other than carbon has been added to be dispersed in carbon at an atomic level to heat treatment within high-pressure press equipment.
