Biotite, known as black mica, is a darker variety of mica that is rich in iron and magnesium. Its color ranges from brown to black, and it is typically opaque rather than transparent. Biotite is primarily found in igneous and metamorphic rocks and tends to form in larger sheets compared to muscovite. While biotite is not as widely used as muscovite, it plays a crucial role in geology, as it is often studied for its weathering processes, which can provide insights into the history of the earth’s crust. In some cases, biotite is used in the production of heat-resistant materials and is also studied for its potential applications in the fields of biomaterials and environmental science.

Mica has a wide range of uses, in ancient China, it is often used to do traditional Chinese medicine, the ancients even think that taking mica: a year to remove all diseases (heavy metal poisoning), three years of long service, husband into a boy (body scrap), Zhongshan uncle Qing suit, over time can become a cloud (soul ascension). However, in the era without glass, the transparency of mica makes it a better decorative material, for example, we are familiar with the mica screen candle shadow deep, the river gradually falling Xiaoxing sink. Mica screen is low, tassel tent is small and mica calf car.

The mica variety that does not contain iron is colorless in flakes, and the higher the iron content, the darker the color, and the more polychromatic and absorbable it is. According to the different chemical composition and optical characteristics, mica group minerals can be divided into Muscovite subgroup, biotite-phlogopite subgroup and lemica subgroup. The common mica are biotite, phlogopite, Muscovite and so on.

Applications and Future Prospects

One of the significant advantages of synthetic mica production is the ability to control its properties precisely. Manufacturers can adjust the size, shape, and chemical composition of the flakes depending on their intended application. This control leads to a product that is not only visually appealing but also functionally superior to its natural equivalent.
