1. A textured particle comprising:
an inner core; and
a spherical solid outer shell comprising an outer surface, wherein the inner core is inside the outer shell, the outer shell comprises a first tier texture between the outer surface and the inner core, the first tier texture comprising a first metal that is greater than 50 atomic % of a total atomic content of all metals in the first tier texture, wherein the first tier texture comprises cracks between the outer surface and the inner core, and the outer surface comprises
a second tier texture comprising a second metal, wherein the second metal is greater than 50 atomic % of a total atomic content of all metals in the second tier texture, and
a third tier texture comprising a third metal, wherein the third metal is greater than 50 atomic % of a total atomic content of all metals in the third tier texture;
wherein the first metal, second metal, and third metals are different metals, and
wherein the second tier texture is on the cracks in the first tier texture, and the third tier texture is on a surface of the second tier texture.
