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.

The common characteristics of mica group minerals are: layered silicate minerals, monoclinic crystal system, a few trigonal crystal system, the crystals are pseudo-hexagonal columnar, plate and sheet; The aggregate is scaly and foliaceous. It has a set of extremely complete cleavage, along which it is easy to peel into sheets. Therefore, the shape of mica is usually regarded as sheet.

X represents large interlayer cations, such as K+, Na+, Ca2+, Ba2+, Rb+, Cs+, etc. Y represents octahedral cations, such as Al3+, Fe2+, Mg2+, Cr3+, Ti4+, Fe3+, etc. Z is mainly Si4+ and Al3+; The ideal ratio of the additional anion (OH)- to (O)2- is 2:10, and (OH)- can be replaced by F- and Cl-. Most mica contain 4% to 5% water. Therefore, although they may be called mica, the chemical composition of different mica may be very different, for the purpose of research, we collectively refer to the minerals with this type of characteristics as mica group minerals.  

One of the benefits of mineral makeup is its long-lasting wear, and natural mica powder for cosmetics plays a role in this durability. Mica powder creates a barrier that helps lock in moisture and prevents the makeup from fading throughout the day. Additionally, mica powder is non-comedogenic, meaning it won’t clog pores or contribute to breakouts, making it a safe option for those with sensitive or acne-prone skin.

Another advantage of external wall insulation paint is its ease of application. Unlike traditional insulation methods that may require extensive construction work, insulation paints can often be applied quickly and with minimal disruption. This makes it an ideal choice for both new builds and renovations. Homeowners can usually apply the paint themselves, or they can hire professionals for a more thorough application, ensuring that the walls benefit optimally from the coating.

2. Mixed Media Mica pigments are perfect for mixed media projects. They can be incorporated into collage, sculpture, and other dimensional artworks. The reflective quality of mica adds an unexpected twist to traditional mixed media techniques, making each piece unique.

4. Improved Reflectivity The reflective properties of pearl pigments not only enhance aesthetics but also have practical benefits. Enhanced reflectivity can improve visibility in low-light conditions, adding a level of safety for drivers. Moreover, light-reflective surfaces can help in maintaining cooler temperatures inside vehicles, potentially increasing comfort during hot weather.

Biotite, often referred to as black mica, is another well-known type of mica. Unlike muscovite, biotite is rich in iron and magnesium, giving it a dark, opaque appearance. This mineral is primarily used in the construction industry, particularly in producing roofing materials and as a filler in asphalt. Biotite's unique properties give it good thermal stability and resistance to chemical weathering, making it an excellent choice for outdoor applications. Additionally, biotite serves as an essential source of potassium in soil, benefiting agricultural practices.

The versatility of mica powder is also one of its main draws in the cosmetic industry. It can be found in everything from mineral foundations to lipsticks and blushes. It blends seamlessly with other ingredients, providing a wide range of finish options—from matte to satin to high-shine. This adaptability makes mica powder indispensable for cosmetic formulations aimed at various skin tones and preferences.

The rapid development of new energy vehicles, batteries and other emerging industries also provides a new application scenario for mica products, such as power battery modules and energy storage system of mica cover plate, mica partition, mica monitoring board and composite mica tape and other products, the application of mica provides the industry with a fire safety solution.
