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.
Understanding Gold Mica Powder
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.
As consumers become more eco-conscious, the demand for sustainable and non-toxic pigment options has risen. Many manufacturers are responding by creating pearl pigments derived from natural sources, ensuring that they are safe for both the environment and the end-user. These sustainable alternatives contribute to a greener supply chain while still delivering the same captivating effects.

Fluorophlogopite mica, a member of the mica group, is an interesting mineral that has garnered attention due to its unique chemical composition and physical properties. As a phyllosilicate mineral, its structure features a two-dimensional framework of silicate tetrahedra and octahedra, resulting in the perfect cleavage that is characteristic of micas. Fluorophlogopite is particularly notable for its inclusion of fluorine in its composition, which differentiates it from its closely related counterpart, phlogopite.
For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.
