Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:
In short, there are significant differences between natural mica powder and synthetic mica powder in production methods, color and appearance, performance characteristics, application fields, and price and cost. Synthetic mica powder is superior to natural mica powder in terms of high temperature resistance, transparency, electrical insulation, stability and mechanical properties, while natural mica powder has more advantages in resource acquisition, cost and color. When choosing which type of mica powder to use, you can consider the high temperature resistance of the required material, electrical insulation performance, transparency and color requirements, evaluate the mechanical strength and hardness of the required material, consider chemical stability and other different application scenarios and technical requirements to make a reasonable choice.
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.

Natural high quality Muscovite:feel fine, soft lubrication.
Additionally, when used in lip products, mica must meet specific regulatory standards. In the United States, the Food and Drug Administration (FDA) regulates the use of color additives, including mica, to ensure they are safe for human use in cosmetics.
Mica powder tumblers are not just visually appealing; they also hold practical benefits. The lasting finish and vibrant colors make them perfect for personal use or as gifts. They make excellent custom creations for weddings, parties, or seasonal events. Moreover, creating these tumblers can be a therapeutic activity, fostering creativity and relaxation.
Synthetic 120 mesh :large particle size, with pearl shining effect.
นอกจากการใช้งานที่ได้กล่าวมาแล้ว ผงมิก้ายังมีบทบาทในอุตสาหกรรมอื่น ๆ เช่น การผลิตเส้นใยและวัสดุที่มีความยืดหยุ่น เช่น สายไฟ เนื่องจากมิก้าเป็นวัสดุที่ไม่สามารถนำไฟฟ้าได้ จึงช่วยเพิ่มคุณสมบัติการเป็นฉนวนได้เป็นอย่างดี
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.
- Layering Technique For depth, consider using multiple layers of colored epoxy. Pour one layer, let it partially cure, then add another layer with a different color.

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.
- Cosmetics The beauty industry is perhaps the most prominent user of mica-based pigments. Their light-scattering effects enhance the appearance of products like eyeshadows, lip glosses, and foundations, imparting a luminous finish. Additionally, their non-toxic properties make them suitable for skin contact applications.
It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.
The mica industry is undergoing profound changes. With the help of emerging industries, the mica industry will be a large market of more than 10 billion.
