ABSTRACT:
According to various aspects of the present invention, a superabrasive element includes a plurality of superabrasive grains (e.g., as diamond grains and/or cubic boron nitride grains). The superabrasive element further includes a binder constituent that bonds at least a portion of the superabrasive grains together. The binder constituent includes predominantly one or more inorganic-compound phases, such as boron or silicon compounds. Applications utilizing such superabrasive elements and methods of fabricating such superabrasive elements are also disclosed.
