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.
These components require materials with non-toxic, odorless, corrosion-resistant, and easy to disinfect properties, and modified plastics can meet these requirements.

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.

Natural mica powder and synthetic mica powder have differences in production methods, heat resistance and color transparency. As the name suggests, natural mica powder is made from natural mica ore after processing, retaining the original characteristics and composition of the ore. Its main components are SiO2 (about 49%) and Al2O3 (about 30%), while also containing K2O+Na2O (9%-11%) and so on. The synthetic mica powder (such as fluoroglogopicite powder), is the use of a variety of raw materials through high temperature reaction and other chemical methods synthetic, its composition and characteristics can be adjusted and optimized according to the need, the chemical formula is KMg3(AlSi3O10)F2, belongs to the monoclinic crystal system, is a typical layered silicate, relatively single and pure composition. The heat resistance of natural mica powder is generally 500-600℃, and some types, such as phlogopite, can reach 800℃. The heat resistance of synthetic mica powder is more excellent, and it can withstand high temperatures above 1200℃, and the melting point or crystallization temperature is about 1375±5. The transparency of natural mica powder is relatively low, and the color is diverse, including black, yellow, white, gray, green, brown and other colors, and may vary due to different ore types and processing methods. The color of synthetic mica powder is relatively single, usually colorless transparent or white, high whiteness, good optical performance, and high transmittance from ultraviolet to infrared band.
Moreover, the reflective qualities of mica give cosmetics a shimmering effect, which is often desirable in products aimed at achieving a dewy, youthful complexion. It is not just limited to makeup; mica is also found in lotions and creams, where it adds a subtle glow to the skin.
China's involvement in mica production dates back several decades. Over the years, the country has developed a robust mica industry, with large-scale mining operations primarily located in regions like Liaoning, Xinjiang, and Jiangsu. Various grades of mica are extracted, serving different industrial applications. China's production capacity makes it a dominant player in the mica market, supplying not only the domestic demand but also catering to international markets.

Huajing mica cosmetic grade mica powder has been loved by customers since it entered the market, and has a general response, excellent quality, stable quality and high reputation.
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?
1. Electronics The electronics industry is one of the primary consumers of MICA. Its electrical insulating properties make it ideal for capacitors, insulators, and other electronic components. As China solidifies its position in the global tech arena, the demand for high-quality MICA will only increase.
Enhances Appearance: Mica enhances the visual appeal of cosmetic products by providing depth, luminosity, and shimmer without making the skin appear oily or greasy.
For example, some certification programs require that mica mines provide safe working conditions, ensure fair wages, and eliminate child labor. Additionally, these programs often promote environmentally responsible mining techniques, such as reforestation and erosion control, to mitigate the negative effects of mining on local ecosystems.
While mica powder offers numerous benefits, it is essential to address ethical sourcing. The mica mining industry has faced scrutiny due to reports of child labor and unsafe working conditions, particularly in regions where mica is harvested. As a response, many cosmetic brands are now committed to using responsibly sourced mica, ensuring that their ingredients are obtained without exploitation.
Pearlescent pigments have carved out a niche in the cosmetic industry, transforming ordinary products into extraordinary creations. Their ability to provide depth, versatility, and an element of luxury continues to captivate consumers worldwide. As the beauty industry pushes the boundaries of innovation, pearlescent pigments will undoubtedly remain at the forefront of cosmetic formulations, enchanting users and igniting creativity for years to come. Whether you're a makeup aficionado or a casual user, embracing the magic of pearlescent pigments could enhance your beauty routine in delightful ways.
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.
Natural mica powder and synthetic mica powder also have great differences in electrical insulation, mechanical properties, chemical stability, application range and cost. Natural mica powder has good electrical insulation, but the volume resistivity is lower than that of synthetic mica. Synthetic mica powder has better electrical insulation properties, high volume resistivity and stable dielectric constant, and is suitable for high performance electrical insulation materials. The hardness of natural mica powder is relatively low (2-3), and it has good elasticity and peeling property. The hardness of synthetic mica powder is higher (between 3 and 4), and the tensile strength and compressive strength are better than that of natural mica powder. Natural mica powder is stable in acid-base solution, but it is easy to decompose at high temperature. Synthetic mica powder is stable to acid and base at room temperature, but will be slowly corroded by sulfuric acid above 300℃. Better thermal stability, not easy to release gas. Natural mica powder is widely used in electrical appliances, welding rods, rubber, plastics, paper making, paint and other fields. Synthetic mica powder is mainly used in high-end electrical insulation materials, aviation, aerospace, national defense industry and other high-tech fields. Because synthetic mica powder needs to be produced through complex chemical processes, its production cost is usually higher than that of natural mica powder. Therefore, in the market, the price of synthetic mica powder is often higher than that of natural mica powder. However, with the continuous progress of production technology and the gradual emergence of scale effects, the price of synthetic mica powder is expected to gradually decrease.
