Abstract:
The formed ceramic abrasive particle includes a plurality of ceramic oxides. The particle further includes a first plurality of oxides, a second plurality of oxides, or a mixture thereof. The first plurality of oxides includes an oxide of yttrium, praseodymium, samarium, ytterbium, neodymium, lanthanum, gadolinium, dysprosium, erbium, or a combination thereof. The second plurality of oxides includes an oxide of iron, magnesium, zinc, silicon, cobalt, nickel, zirconium, hafnium, chromium, cerium, titanium, or a combination thereof. The formed ceramic abrasive particle further includes a plurality of edges, each edge having a length independently ranging from about 0.1 μm to about 5000 μm. The formed ceramic abrasive particle further includes a tip defined by a junction of at least two of the edges, the tip can have a radius of curvature ranging from about 0.5 μm to about 80 μm.
