Calcined Mica Nanopowder

Calcined Mica Nanopowder

Mica has acid, alkali, chemical stability, heat resistance, non-flammable, good insulation. The main purpose: it is used in the field of construction materials, on behalf of asbestos products and also for extinguishing agents, welding, plastics, rubber, paints, coatings, chemicals, electronic products, oil well drilling, pearlescent pigments, and other areas of work. For example: add moist ultrafine mica, protect ultraviolet light, improve coating wear resistance, delay staining, discolor; a two-dimensional sheet metal structure with a high aspect ratio, improves the general mechanical properties of the coating, water resistance, anti-crack, improves tolerance and self-cleaning; Acid, alkali, high temperature, improves thermal coating and corrosion resistance.

Applications

Electronics and Electrical Insulation

Calcined mica nanopowder is highly valued in the electronics industry for its excellent insulating and dielectric properties. It is used in several electronic components where high thermal and electrical stability is required.

Electrical Insulation: Mica has long been a staple material for insulating electrical components. When reduced to nanopowder form, it retains its insulating characteristics while offering increased surface area and better performance in high-voltage and high-temperature applications, such as transformers, motors, and capacitors.

Capacitors and Resistors: Mica nanoparticles are incorporated into capacitors, resistors, and other passive components to improve their thermal conductivity and dielectric strength, especially in high-frequency circuits.

Thermal Management: Due to its high thermal conductivity, calcined mica nanopowder is used in the production of materials designed for heat dissipation in electronic devices, semiconductors, and LED lights.

Cosmetics and Personal Care

Cosmetic Pigments: One of the most common uses of calcined mica nanopowder is in makeup products such as eyeshadows, highlighters, blushes, and foundations. Its reflective properties provide a shimmery finish to cosmetics, offering a natural luminous effect without the use of harsh chemicals.

Skin Care: In addition to being a pigment, calcined mica nanopowder is sometimes used in skin care formulations for its mild abrasive properties, helping with exfoliation. It is included in facial scrubs, masks, and cleansers to remove dead skin cells and enhance skin texture.

Sun Protection: Some sunscreens and sunblocks use calcined mica nanopowder as a physical UV filter. The nanoparticle form allows the mica to create a protective barrier against harmful UV rays, providing enhanced sun protection without causing irritation.

 Paints, Coatings, and Pigments

Surface Coatings: Mica nanopowder is often used as a functional filler in industrial coatings and paints. It improves the durability and scratch resistance of the coatings while enhancing their aesthetic finish with a glittery effect. This makes it suitable for applications in automotive, architectural, and furniture coatings.

Anti-corrosion Coatings: Calcined mica is also employed in anti-corrosion coatings due to its inert nature and resistance to chemical degradation. It helps prevent rust and wear, extending the lifespan of metal surfaces in marine, industrial, and outdoor environments.

Reflective Coatings: Mica nanopowder is used in reflective coatings for road signs, safety markings, and traffic signals. The reflective properties of the powder increase visibility, especially at night or in low-light conditions.
