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.

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

The Vibrant World of Mica Powder Factories

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.

One of the defining features of video mica is its ability to engage audiences on multiple levels. The interplay between the fluctuating audio-visual elements can evoke a range of emotions, from serene contemplation to vibrant excitement. In some instances, video mica works resemble living scrolls, continuously unfolding with ever-changing visuals that mirror the fluidity of our experiences in the modern world. These pieces have the capacity to tell stories that resonate on a deeply personal level, connecting viewers with the broader themes of existence, time, and permanence.

When it comes to crafts, such as resin art or soap manufacturing, mica powder may be blended with various binders and carriers. These can include glycerin for soaps, epoxy resin, or even water to dissolve the mica powders for easier application. Additionally, when using mica in food products, it's crucial to ensure that the colorants and additives are food-grade and safe for consumption.

Finally, mica's impact on China's economy cannot be overstated. By driving multiple industries and fostering technological advancement, mica has become a pivotal element in China's industrial narrative. It contributes significantly to export revenues, creating jobs and fostering economic stability. As such, mica is not just a mineral but a cornerstone of China’s sustained industrial growth and global trade dominance.

Oxides and Ultramarines These pigments are suitable for a more matte finish and are often used in professional formulations. They are available in various colors and can be combined with other natural alternatives to create unique shades.
