A group of parallel cleavages can be seen in a photograph of biomica under orthogonal polarized (left) and single polarized (right) mirrors.
Mica powder, known as industrial monosodium glutamate, is widely used. With the continuous development of technology and application market, and some new requirements have been put forward for the quality of mica powder, so synthetic mica powder has been developed. Compared with the natural mica powder processed by natural mica ore, and the synthetic mica powder synthesized by using a variety of raw materials through high temperature reaction and other chemical methods. What are the advantages and differences between them?
Natural high quality Muscovite:feel fine, soft lubrication.
As the demand for ethical and sustainable ingredients continues to rise, exploring alternatives to mica powder has become increasingly important. By considering natural and synthetic substitutes, along with creative combinations, you can develop products that not only meet your aesthetic goals but also align with your values. Whether you're a cosmetic formulator, an artist, or a DIY enthusiast, the options discussed above can inspire new creations while minimizing environmental and ethical concerns. Remember, the key is to experiment and find the right balance that works for your specific needs.
Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.

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.
While mica powder is generally considered safe for use, it is essential to source it from reputable suppliers that adhere to industry regulations. In cosmetic applications, mica must be free from heavy metals and contaminants to ensure consumer safety. Therefore, always check for certifications and lab testing results when purchasing mica powder.
The mica powder of HUAJING has the advantage of extremely narrow particle size, and the particle size specifications are complete, such as: 2000 mesh, 1250 mesh, 800 mesh, 400 mesh, 120 mesh, etc. The skin feeling is exquisite.
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 { Y2-3 [Z4O10] (OH)2 }
For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.
What are the uses of mica
Shimmer pigment powder is a type of fine powder composed of various minerals and synthetic materials that create a reflective quality. These pigments come in a wide array of colors and finishes, ranging from subtle pastels to bold metallic hues. The shimmer effect is achieved through the inclusion of mica, a natural mineral that reflects light effectively, giving the powder its characteristic luster.
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.
Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.
