In addition to its vibrant colors, epoxy mica powder also enhances the durability of the final product. When cured, the epoxy resin forms a hard, resilient layer that protects against moisture, UV light, and various environmental factors. This makes it an excellent choice for outdoor applications, where resistance to fading and degradation is crucial.

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.

Phlogopite is another type of mica that is similar to biotite but contains more magnesium and less iron, leading to a lighter color that ranges from golden brown to a pale green hue. It is predominantly found in metamorphic rocks, particularly those formed under high-temperature conditions. Phlogopite is especially valued in applications requiring thermal resistance, such as in the manufacturing of refractory materials and as a filler in various industrial applications. Its high dielectric strength also makes it suitable for electrical insulation, similar to muscovite.

The automotive industry also benefits from this amazing pigment. Pearl white finishes on cars are highly sought after for their aesthetic appeal, offering a luxurious touch that stands out. Manufacturers often employ pearl white pigments in the paint formulations to achieve that coveted iridescent effect, captivating car enthusiasts and consumers alike.

While video mica is a celebration of contemporary practice, it also encourages a dialogue about sustainability and the ethical implications of art creation. The use of natural materials, such as mica, raises questions about resource extraction and environmental impacts, prompting artists and audiences alike to consider the balance between creativity and conscience. This critical engagement adds another layer of complexity to the discourse surrounding video mica, encouraging a more holistic understanding of art in our interconnected world.

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.
