The rapid development of new energy vehicles, batteries and other emerging industries also provides a new application scenario for mica products, such as power battery modules and energy storage system of mica cover plate, mica partition, mica monitoring board and composite mica tape and other products, the application of mica provides the industry with a fire safety solution.

Mica is a naturally occurring mineral that forms in layers, giving it a unique structure that allows it to be ground into a fine powder. It is available in various colors and is often used in products such as eyeshadows, blushes, highlighters, and nail polishes. Besides its aesthetic qualities, mica powder also offers benefits like oil absorption, improved texture, and increased blendability in formulations.

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

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 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?

Natural mica powder is a remarkable ingredient that adds both beauty and functionality to cosmetic formulations. Its versatility, safety, and desirable aesthetic properties make it an excellent choice for a wide range of beauty products. As consumers continue to prioritize natural and ethically sourced ingredients, the importance of natural mica powder will only grow in the cosmetics industry.

Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.

The mica powder of HUAJING has the advantage of extremely narrow particle size, and the particle size specifications are complete, such as: 2000 mesh, 1250 mesh, 800 mesh, 400 mesh, 120 mesh, etc. The skin feeling is exquisite.

However, the mica supply chain does face ethical challenges, particularly related to artisanal mining practices in some regions. Ensuring fair trade practices and promoting transparency in the mica supply chain is crucial to reduce exploitation and improve the lives of miners and their families.

Furthermore, efforts toward transparency and ethical sourcing are reshaping the mica market. Brands that disclose their supply chains are gaining consumer trust, which can lead to higher market prices for ethically sourced mica powder.

In the dynamic world of mica trading, our firm stands out not only for the quality of products but also for our unparalleled customer service. We provide comprehensive support, from technical guidance on product selection to detailed information on handling and application. Our after-sales service is a testament to our dedication to client satisfaction, ensuring that their experience with our products and services is seamless and beneficial.

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.
