Mica Powder Manufacturer & Supplier in China WANCHENG MINERAL (6).JPG

Calcined Silver Mica Powder from China - Premium Suppliers & Factory for Decorative Applications

Calcined silver mica powder is a high-quality product developed by WANCHENG MINERAL, a leading factory and supplier based in China. Through controlled thermal treatment, natural mica undergoes calcination to enhance its color stability, reduce volatile impurities, and achieve a striking silver appearance. This unique process sets our calcined silver mica apart from ordinary mica powders, resulting in a brighter metallic silver effect that is perfect for decorative and functional applications where both aesthetics and mineral performance are essential. WANCHENG MINERAL specializes in providing coarse mica particles and decorative mica flakes, specifically designed for customers seeking a silver surface effect. Our available specifications include 10 mesh, 20 mesh, and 40 mesh, making these products ideal for achieving visible decorative effects in textured coatings, construction surface materials, functional fillers, insulation layers, and various industrial formulations that benefit from particle visibility and flake texture. Maintaining the natural layered structure of mica, our calcined silver mica exhibits excellent flexibility, thermal resistance, electrical insulation, chemical stability, and surface reflectivity. The result is a cleaner, more uniform surface appearance with a distinct silver color that differentiates it from traditional white, golden, and black mica products. This makes it a valuable special-effect mineral material for decorative systems, coatings, building materials, and other industrial applications. For international customers, WANCHENG MINERAL ensures stable color, precise particle size control, clean packaging, and reliable supply. As a reputable supplier, we offer export-grade packaging, quality inspection, and customized supply support to global distributors, coating manufacturers, construction material factories, and industrial mineral users. Enhance your product range with our premium calcined silver mica powder from China, delivered with the assurance of quality and consistency.

Frequently Asked Questions

What are the primary chemical components of this mineral?

Silicon dioxide (SiO₂) at 42% – 48% and aluminum oxide (Al₂O₃) at 28% – 38% constitute the primary silicate and alumina matrix of the mineral, providing structural stability and thermal resistance.

Why is K₂O (Potassium Oxide) content significant in mica?

Potassium Oxide (K₂O), typically present between 7% and 11%, is a defining alkali component of natural mica minerals, contributing to its layered crystal structure and distinctive electrical insulation properties.

How does Fe₂O₃ concentration affect the final application?

The iron oxide (Fe₂O₃) content (1% – 6%) directly influences color shading, whiteness, and specific mineral characteristics required for industrial coatings, plastics, or cosmetic grades.

What causes the reduction in Loss on Ignition (LOI)?

Loss on Ignition decreases significantly following the calcination process as volatile substances and bound moisture are driven off at elevated temperatures, depending on the thermal processing conditions.

Why are CaO and Na₂O levels maintained at low percentages?

Low levels of Calcium Oxide (CaO ≤ 2%) and Sodium Oxide (Na₂O ≤ 1.5%) ensure minimal impurity interference, maintaining high chemical purity and dielectric performance across end-use formulations.
