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.

In the realm of modern construction and home improvement, external wall insulation has become a crucial topic, especially given the rising concerns related to energy efficiency and environmental sustainability. Among the various methods to improve the thermal performance of buildings, the use of external wall insulation paint is garnering significant attention. This article delves into the benefits, applications, and considerations related to external wall insulation paint.
With the increasing awareness of environmental protection, more and more modified plastics are paying attention to biodegradability and environmental friendliness.
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.
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.
Conclusion
Mica powder is particularly popular for its ability to blend seamlessly with resin, resulting in a smooth, consistent finish that enhances the overall appearance of your work. Unlike traditional pigments, which can be opaque, mica powder provides a translucent effect, allowing the resin to retain its natural clarity while adding subtle color or shimmer. This quality makes mica powder ideal for applications like clear resin coasters, trays, and artwork where you want the light to pass through the resin, revealing layers of color and shine.
- Ingredient Transparency Reputable suppliers will provide clear information about their mica’s sourcing, processing, and any added ingredients.
2. Enhanced Depth and Dimension When added to epoxy, metallic mica powder creates a three-dimensional illusion. The way light interacts with these particles gives depth to the resin, making it more dynamic and visually appealing. This characteristic is particularly valuable for projects like river tables and countertops, where a striking surface is desired.
Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:
Mica is a group of minerals composed primarily of silicate, alumina, and other metallic elements. These minerals can be split into thin sheets, which gives mica its characteristic flexibility and reflective qualities. Mica chips often possess excellent electrical, thermal, and chemical resistance, making them indispensable in many manufacturing processes. They are lightweight, non-toxic, and environmentally friendly, which further enhances their appeal as a raw material.

3. Cosmetics Beyond traditional art, mica pigments have found a significant place in the beauty industry. They are used in eyeshadows, highlighters, and lip products to provide a radiant glow. Artists in cosmetics use mica to formulate shades that are not only beautiful but also safe and natural.
Many of our commonly used eyeshadow and other cosmetics have added natural or synthetic mica materials to achieve the effect of blingbling, these materials are non-toxic and non-irritating, but may contain some heavy metals, but please rest assured that if you buy regular cosmetics, its composition generally meets the requirements of cosmetics heavy metal indicators, harmless to the human body!!
