1. A particulate material comprising:
- a shaped abrasive particle having a body comprising;
a first layer;
a second layer overlying the first layer; and
a diffusion interface disposed between the first layer and the second layer,wherein the second layer comprises a dopant;
wherein the diffusion interface defines a step function difference in a concentration of the dopant in the second layer compared to a concentration of the dopant in the first layer; and
wherein the diffusion interface separates a region of the first layer having a first dopant concentration (D1c) and a region of the second layer having a second dopant concentration (D2c).
