1. A particulate material comprising:
a shaped abrasive particle having a body comprising a length, a width, and a thickness, wherein the body comprises a central region including the geometric center of the body having a first microstructure, the body further comprising an upper surface defined by the dimensions of length and width, the upper surface having a second microstructure, wherein the first microstructure is different from the second microstructure,
wherein the geometric center of the body is essentially free of a dopant material,
wherein an exterior surface of the body comprises a texture comprising protrusions and grooves;
wherein the grooves comprise an amount of a dopant material and the protrusions comprise an amount of a dopant material; and
wherein the amount of dopant material within the grooves is greater than the amount of dopant material at the protrusions.
