Abstract
There is disclosed a method including chemically converting a first material of a lamellar particle into a compound of the first material. The step of chemical conversion can be performed by a reactant, and the reactant can be in a form of at least one of a solid state, a liquid state, a vapor state, and a plasma state.

A method of forming a pigment, comprising:
- chemically converting a portion of a first material of a lamellar particle into a compound of the first material to form a converted lamellar particle in the form of the pigment,
- wherein the converted lamellar particle includes a converted portion and an unconverted portion;
- wherein the converted lamellar particle has a width ranging from about 10 microns to about 50 microns and a thickness from about 0.1 to about 2 microns;
- wherein the chemically converting is performed by introducing the lamellar particle into a chemical bath in a liquid state;
- wherein the chemical bath comprises K2S and 2-Mercaptobenzothiazole;
- wherein at least a part of the unconverted portion comprises a metal chosen from copper, silver, alloys of any of these metals, or a combination thereof, and wherein the converted lamellar particle comprises a chemical compound of the metal.
