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.
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?
Synthetic 120 mesh :large particle size, with pearl shining effect.
- Quality Certifications Ask for certifications that demonstrate the supplier's adherence to industry standards. Certifications from organizations that focus on sustainable and ethical practices are particularly valuable.
- Sealing To preserve the integrity of your mica artwork, consider applying a clear sealant. This will protect the shimmer and prevent any fading over time.
It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.
Benefits of Using Metallic Mica Powder in Epoxy Resin
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.
3. Use less color for transparency If you desire a more transparent effect, simply reduce the amount of mica powder you add.
X { Y2-3 [Z4O10] (OH)2 }
2. Arts and Crafts Artists often incorporate mica flakes into their work to add depth and sparkle to paintings and sculptures. These flakes can be mixed with paints, resins, or used as standalone materials to create unique visual effects.
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.
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.
Synthetic mica is a laboratory-created alternative that mimics the natural properties of mica without the associated ethical and environmental concerns. Produced through a controlled manufacturing process, synthetic mica is composed of the same silicate minerals as its natural counterpart but is synthesized from non-toxic materials. This innovation allows cosmetic companies to formulate products that are visually appealing without compromising their ethical standards.
