20130186005 | FORMING SHAPED ABRASIVE PARTICLES - A method of forming a shaped abrasive particle includes extruding a mixture into an opening in a screen within an application zone and translating the screen and belt to a release zone and separating the screen and belt to form a precursor shaped abrasive particle on the belt, wherein the screen and belt are separated at a release angle of at least about 15° and not greater than about 45°, wherein the release angle is defined as an angle between a surface of the screen and a surface of the belt. | 07-25-2013 |
20130186006 | ABRASIVE PARTICLES HAVING PARTICULAR SHAPES AND METHODS OF FORMING SUCH PARTICLES - A method of forming an abrasive article includes depositing a mixture into an opening of a substrate, contacting an exposed surface of the mixture in the opening to a texturing form to form a textured preform, and removing the mixture from the opening and forming an abrasive particle having a textured surface. | 07-25-2013 |
20130236725 | ABRASIVE PARTICLES HAVING COMPLEX SHAPES AND METHODS OF FORMING SAME - An abrasive grain is disclosed and may include a body. The body may define a length (l), a height (h), and a width (w). In a particular aspect, the length is greater than or equal to the height and the height is greater than or equal to the width. Further, in a particular aspect, the body may include a primary aspect ratio defined by the ratio of length:height of at least about 2:1. The body may also include an upright orientation probability of at least about 50%. | 09-12-2013 |
20140007518 | ABRASIVE PARTICLES HAVING PARTICULAR SHAPES AND METHODS OF FORMING SUCH PARTICLES - A shaped abrasive particle including a body having a length (l), a width (w), and a height (hi), wherein the height is at least about 28% of the width, and a percent flashing (f) of at least about 10% and not greater than about 45% for a total side area of the body. | 01-09-2014 |
20140182216 | PARTICULATE MATERIALS AND METHODS OF FORMING SAME - A particulate material having a body including a first phase having at least about 70 wt % alumina for a total weight of the first phase, and a second phase comprising phosphorus, wherein the body includes at least about 0.1 wt % of the second phase for the total weight of the body, and wherein the second phase has an average grain size of not greater than about 1 micron. | 07-03-2014 |
20140182217 | ABRASIVE PARTICLES HAVING COMPLEX SHAPES AND METHODS OF FORMING SAME - An abrasive grain is disclosed and may include a body. The body may define a length (l), a height (h), and a width (w). In a particular aspect, the length is greater than or equal to the height and the height is greater than or equal to the width. Further, in a particular aspect, the body may include a primary aspect ratio defined by the ratio of length:height of at least about 2:1. The body may also include an upright orientation probability of at least about 50%. | 07-03-2014 |
20140325916 | ABRASIVE PARTICLES HAVING PARTICULAR SHAPES AND METHODS OF FORMING SUCH PARTICLES - 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 (A | 11-06-2014 |
