Calcined Silver Mica Powder

Calcined silver mica powder is a specially processed mica product developed through controlled thermal treatment. During calcination, selected natural mica is heated under controlled production conditions to improve its color stability, remove part of the volatile impurities, and create a distinctive silver appearance. Unlike ordinary natural mica powder, this product presents a brighter metallic silver visual effect after calcination, making it suitable for decorative and functional applications where appearance, stability, and mineral performance are required at the same time.

WANCHENG MINERAL has developed this calcined silver mica product for customers who require coarse mica particles or decorative mica flakes with a silver surface effect. At present, the available specifications are 10 mesh, 20 mesh, and 40 mesh only. These sizes are relatively coarse compared with fine mica powder, so the product is especially suitable for visible decorative effects, textured coatings, construction surface materials, functional fillers, insulation layers, and industrial formulations where particle visibility or flake texture is desired.

The product keeps the natural layered structure of mica. This structure gives the material good flexibility, thermal resistance, electrical insulation, chemical stability, and surface reflection. After calcination, the surface appearance becomes cleaner and more uniform. The silver color makes the product different from traditional white mica, golden mica, and black mica products. It can be used as a special-effect mineral material in decorative systems, coatings, building materials, and other industrial applications.

For international customers, stable color, particle size control, clean packaging, and reliable supply are important factors when choosing calcined mica products. WANCHENG MINERAL provides export-grade packaging, quality inspection, and customized supply support for global distributors, coating manufacturers, construction material factories, and industrial mineral users.

    Technical Specifications

    Calcined silver mica powder from WANCHENG MINERAL is currently supplied in three available specifications: 10 mesh, 20 mesh, and 40 mesh. 

    The 10 mesh grade has large visible flakes and is suitable for decorative aggregate effects, surface texture materials, and applications where strong visual particle appearance is required. The 20 mesh grade provides a balanced particle size for decorative coatings, construction materials, and functional filler applications. The 40 mesh grade is finer than 10 mesh and 20 mesh, while still retaining visible flake texture and silver appearance.

    The specifications listed below are typical reference values. Final data may vary according to raw material source, production batch, calcination temperature, and customer requirements. WANCHENG MINERAL can provide batch inspection and product samples for customer evaluation before bulk orders.

    Advantages
    Packaging
    Production Process

    The calcined silver mica powder developed by WANCHENG MINERAL has several advantages for industrial and decorative applications.

    1. Unique Silver Appearance

    After calcination, the product presents a silver tone that is different from ordinary mica products. This makes it suitable for decorative surface materials and visible mineral effect formulations.

    2. Natural Flake Structure

    The layered structure of mica supports good reflection, flexibility, and barrier performance. It also helps create visible texture in coarse-grade applications.

    3. Heat Resistance

    Calcined mica offers good thermal stability and can be used in certain heat-resistant and refractory formulations.

    4. Chemical Stability

    Mica is chemically stable under many industrial conditions and has good resistance to weathering and aging.

    5. Controlled Coarse Particle Sizes

    WANCHENG MINERAL currently supplies 10 mesh, 20 mesh, and 40 mesh, which are suitable for customers requiring visible silver mica flakes or coarse mineral filler.

    6. Export Supply Support

    WANCHENG MINERAL provides professional export packaging, stable supply, sample support, and customized service for global customers.

    Proper packaging is important for calcined silver mica powder because the product needs to maintain dry condition, clean appearance, and stable particle size during transportation and storage. WANCHENG MINERAL provides export-grade packaging suitable for international shipment.

    Common packaging options include 25kg PP woven bags, 25kg kraft paper bags, jumbo bags, palletized packaging, and OEM packaging. For coarse mica grades such as 10 mesh and 20 mesh, packaging should avoid excessive compression and rough handling to reduce particle breakage.

    Products should be stored in a dry, clean, and ventilated warehouse. Customers should avoid moisture, oil contamination, direct rain exposure, and damaged packaging during storage.

    WANCHENG MINERAL follows a controlled production process to ensure stable calcined silver mica quality.

    1. Raw Mica Selection

    Selected natural mica is chosen based on color, flake structure, impurity level, and suitability for calcination.
