    Abstract: An abrasive article includes a shaped abrasive particle including a body having a first height (h1) at a first end of the body defining a corner between an upper surface, a first side surface, and a second side surface, and a second height (h2) at a second end of the body opposite the first end defining an edge between the upper surface and a third side surface, wherein the average difference in height between the first height and the second height is at least about 50 microns. The body also includes a bottom surface defining a bottom area (Ab) and a cross-sectional midpoint area (Am) defining an area of a plane perpendicular to the bottom area and extending through a midpoint of the particle, the body has an area ratio of bottom area to midpoint area (Ab/Am) of not greater than about 6.

    Abstract translation: 磨料制品包括成形的磨料颗粒，该磨料颗粒包括在本体的第一端处具有第一高度（h1）的主体，该第一高度限定了上表面，第一侧表面和第二侧表面之间的角，以及第二高度（h2） ），其在所述主体的与所述第一端相对的第二端处限定在所述上表面和第三侧表面之间的边缘，其中所述第一高度和所述第二高度之间的平均高度差为至少约50微米。 主体还包括限定底部区域（Ab）的底表面和限定垂直于底部区域并延伸穿过颗粒中点的平面区域的横截面中点区域（Am），所述主体具有面积比 底面积至中点面积（Ab / Am）不大于约6。
