-15 Synthetic Mica Powder | Ultra-Fine & High Purity
Industry Trends: The Shift Towards Synthetic Purity
The global market for high-performance minerals is undergoing a significant transformation. Industries traditionally reliant on natural mica are now rapidly migrating towards synthetic alternatives. This shift is driven by a demand for higher purity, greater consistency, and ethical sourcing—all hallmarks of materials like -15 Synthetic Mica Powder. According to recent market analysis, the synthetic mica market is projected to grow at a CAGR of over 6.5% through 2028, with the cosmetics and electronics sectors leading this charge. The key drivers include stricter regulations on heavy metal content (e.g., lead, mercury, arsenic) in consumer products and the need for materials that can withstand extreme processing temperatures in advanced polymers and coatings. -15 Synthetic Mica Powder, with its chemically controlled composition, offers a reliable solution, free from the geological impurities and sourcing concerns associated with its natural counterpart.

Unveiling the Manufacturing Excellence of -15 Synthetic Mica Powder
From Raw Elements to Refined Powder: The HJMICA Process
The superior quality of our -15 Synthetic Mica Powder is not a matter of chance; it is the result of a meticulously controlled manufacturing process, adhering to ISO 9001:2015 quality management standards. Unlike mined natural mica, our synthetic fluorphlogopite is "grown" in a lab-like environment, ensuring unmatched purity and structural integrity.
Stage 1: High-Purity Raw Material Fusion
We begin with a precise blend of high-purity raw materials including silica, alumina, potassium carbonate, and magnesium oxide. These are melted in an internal-heating electric furnace at extreme temperatures exceeding 1450°C (2642°F) to form a homogenous molten silicate.
Stage 2: Controlled Crystallization & Cooling
The molten mass undergoes a slow, controlled cooling process. This critical stage allows large, perfect mica crystals (Synthetic Fluorphlogopite) to form and grow, creating a highly ordered lamellar structure essential for its unique optical and physical properties.
Stage 3: Grinding, Milling & Classification
The solidified mica crystals are then subjected to advanced grinding and milling techniques. The material is carefully processed to achieve a specific particle size distribution (PSD). For -15 Synthetic Mica Powder, this means milling to an ultra-fine state where the majority of particles are below 15 micrometers.
Stage 4: Rigorous Quality Control & Testing
Every batch undergoes stringent testing using advanced analytical equipment. We verify particle size with laser diffraction analysis (ASTM D4464), assess purity via X-ray fluorescence (XRF), and confirm whiteness and brightness using colorimetry, ensuring every shipment meets our exacting specifications.

Frequently Asked Questions (FAQ)
Synthetic Fluorphlogopite, with the chemical formula KMg₃(AlSi₃O₁₀)F₂, is a man-made mica. It is synthesized by melting and crystallizing high-purity raw materials at very high temperatures. This process results in a mica that is structurally similar to natural phlogopite mica but with fluorine (F) replacing the hydroxyl group (OH). This substitution is key to its higher thermal stability and its superior purity, as it is free from the heavy metals and other impurities commonly found in mined mica.
The "-15" refers to the particle size of the powder, specifically indicating that it is an ultra-fine grade. It generally means that the top-cut size is 15 micrometers (µm), or that the D90/D95 value (90%/95% of the particles by volume) is below 15 µm. This extremely fine particle size is crucial for applications requiring a smooth, silky texture (like cosmetics) or a flawless, high-gloss surface finish (like automotive coatings).
Our -15 Synthetic Mica Powder offers three key advantages over natural mica:
1. Purity: It has virtually no heavy metals or mineral impurities, leading to brighter colors and enhanced safety.
2. Heat Resistance: It is stable up to 1100°C, compared to ~600°C for muscovite and ~850°C for natural phlogopite mica, preventing yellowing in high-temperature processes.
3. Consistency: Being lab-made, every batch has identical particle size, shape, and purity, ensuring reliable and repeatable results in your final product.
Absolutely. Our -15 Synthetic Mica Powder is manufactured to meet the stringent requirements for cosmetic use globally. The heavy metal content (e.g., lead, arsenic, mercury, cadmium) is well below the limits set by authorities like the US Food and Drug Administration (FDA) and the European Commission Regulation (EC) No 1223/2009. We provide all necessary documentation for regulatory submissions upon request.
Synthetic mica is an extremely stable inorganic material. When stored in its original, unopened packaging in a dry, cool environment away from direct sunlight, it has an indefinite shelf life. We recommend keeping it in a sealed container111 after opening to prevent moisture absorption, which could affect its flowability, although its chemical properties will remain unchanged.
Yes, customization is one of our core strengths. While "-15" is a standard fine grade, we can work with your R&D team to develop a custom Particle Size Distribution (PSD) tailored to your needs. Whether you require a narrower distribution for a specific optical effect or a different D50 value for rheological control, our advanced milling and classification technology allows for precise adjustments.
We employ a multi-stage QC process. Key tests include:
• Laser Diffraction Analysis (e.g., Malvern Mastersizer): To precisely measure and verify the particle size distribution (D10, D50, D90).
• X-Ray Fluorescence (XRF): To confirm the chemical purity and absence of contaminants.
• Colorimetry: To measure whiteness, brightness (L*a*b* values) and ensure batch-to-batch color consistency.
• Bulk Density & Oil Absorption Tests: To ensure consistent physical properties for formulation.
A full Certificate of Analysis (COA) is provided with each shipment.
