Abstract
A thermostable abrasive diamond product includes a compact formed of diamond grains representing more than 80% by volume of the compact, each grain being bonded directly to its neighbors so as to form a polycrystalline structure. The empty spaces between diamond grains are occupied by a binder face containing silicon and/or titanium and nickel silicon (or titanium) and nickel being alloyed. The compact may be bonded by a metallurgical interface to a substrate of a refractory metal such as tungsten.
