Abstract
A particulate material having a body including a dopant contained in the body, the dopant is non-homogenously distributed throughout the body and the body has a maximum normalized dopant content difference of at least 35%.
Claims19
An abrasive particulate comprising a body and a dopant contained in the body, wherein the dopant is non-homogenously distributed throughout the body and defines the following regions in the body:
- an enriched region abutting an exterior surface of the body and having a first dopant content;
- a doped region in a central region of the body and different than the enriched region, the doped region having a second dopant content;
- and
- a depletion region between the enriched region and doped region, the depletion region defining a decrease in the normalized content of the dopant of at least 0.04%/nm.
An abrasive particulate comprising a body and a dopant contained in the body, wherein the dopant is non-homogenously distributed throughout the body and wherein the body comprises a maximum normalized dopant content difference of at least 35%.
A method of forming an abrasive particulate comprising a body, the method comprising:
- comminuting a particulate precursor;
- impregnating the particulate precursor;
- and
- conducting an enriching process and selectively depositing a dopant in higher concentrations in an enriched region of the body of the abrasive particulate compared to a doped region of the body, the doped region being associated with a central region of the body, and wherein the body comprises a maximum normalized dopant content difference of at least 35%.
