The mica industry faces numerous challenges, particularly concerning labor practices. In many regions, mica mining operations have been linked to child labor and unsafe working conditions. These issues have drawn scrutiny from various organizations and consumers, prompting calls for greater transparency and accountability within the supply chain. Many companies are now adopting strict sourcing policies to ensure that they procure mica from ethical sources.
Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:
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?
Synthetic matte 2000 mesh:fine skin, matte effect.
Natural high quality Muscovite:feel fine, soft lubrication.
2. Enhanced Thermal Stability Mica's natural thermal resistance makes it an ideal additive for soft plastics that are exposed to varying temperatures. This quality is critical in applications such as automotive interiors, where materials must endure fluctuations in temperature without degrading or losing their structural integrity. The thermal stability that mica powder imparts extends the lifespan of soft plastic products, making them a more sustainable choice.
In highlighters, for example, mica particles catch and reflect light, giving the skin a dewy, illuminated look. This is especially popular in products designed for achieving a glowing complexion. Mica is used to give eyeshadows their shimmer and shine, allowing for a metallic or pearlescent finish that enhances the eyes' natural contours. The ability to create these visually striking effects makes mica an indispensable ingredient in many cosmetic products.
It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.
In 2022, Lingshou Huajing Mica Co., Ltd. launched cosmetic grade mica powder. The flake structure of mica powder can lock the water on the surface of the skin, forming a protective film to effectively prevent water loss. Its unique gloss and reflection effect add natural and charming luster to the skin, and mica powder also has a certain sunscreen effect. To a certain extent, it can reduce the damage of ultraviolet rays on the skin, protect the skin from the external environment, and prevent sunburn.

นอกจากการใช้งานที่ได้กล่าวมาแล้ว ผงมิก้ายังมีบทบาทในอุตสาหกรรมอื่น ๆ เช่น การผลิตเส้นใยและวัสดุที่มีความยืดหยุ่น เช่น สายไฟ เนื่องจากมิก้าเป็นวัสดุที่ไม่สามารถนำไฟฟ้าได้ จึงช่วยเพิ่มคุณสมบัติการเป็นฉนวนได้เป็นอย่างดี

La poudre de mica est un minéral naturel, souvent utilisé dans divers domaines grâce à ses propriétés uniques. Cette substance, qui se présente sous forme de flocons brillants, est prisée pour sa capacité à réfléchir la lumière et à apporter une texture lisse et soyeuse à de nombreux produits. Dans cet article, nous allons explorer les multiples utilisations de la poudre de mica, notamment dans les secteurs de la cosmétique, de l'artisanat, et de l'industrie.
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 high quality Muscovite:feel fine, soft lubrication.
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.
Mica is a new non-metallic crystal material, a national key new material, with heat insulation, insulation, high temperature resistance characteristics, is an important material in aerospace, rail transit, nuclear power, wind power, aircraft carriers and other high-tech fields, but also electrical equipment, wire and cable, household appliances indispensable insulation material, in the national economy and national defense construction plays an important role.
Epoxy resin has gained immense popularity in recent years, particularly among crafters and DIY enthusiasts. When combined with mica powder, it transforms into a medium that is not only functional but also stunningly beautiful. In this article, we will explore the fascinating world of epoxy with mica powder, discussing its applications, the mixing process, and tips for achieving stunning results.

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.
It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.
