Sentences with phrase «iron oxide particles»

"Iron oxide particles" refers to very tiny pieces of a compound called iron oxide. It is a substance that is formed when iron combines with oxygen. These particles can come in different colors, such as red, brown, or yellow, and are often used in things like paint and cosmetics because of their coloring properties. Full definition
