Black Mica (Abrak Siyah) ابرک سیاہ

Overview

“Black mica” typically refers to a type of mica mineral known as biotite. Biotite is a common phyllosilicate mineral within the mica group, characterized by its dark coloration, usually ranging from dark brown to black. Like other types of mica, biotite has a layered structure with excellent cleavage and is composed of thin, flexible sheets.Biotite, or black mica, is primarily composed of potassium, magnesium, iron, aluminum, silicon, and oxygen. The presence of iron imparts its characteristic dark color. In its natural form, black mica appears as thin, flaky sheets or aggregates with a dark brown to black color. It often has a metallic luster, especially when its surface is freshly cleaved. It can be used in the production of certain paints, pigments, and coatings to achieve dark or black coloration. Additionally, it is sometimes used in decorative applications, such as countertops and tiles, where its dark color can provide a striking contrast.
