Professional FAQ: 60 mesh Calcined Mica Powder Manufacturer Terminology Explained

1. What is "calcined mica powder" and how does it differ from regular mica powder?: Calcined mica powder is produced by subjecting natural mica flakes to controlled heating above 900°C. This thermal process removes volatile components, increases crystallinity, and enhances chemical stability. Compared to untreated mica powder, calcined varieties display improved electrical insulation, better color brilliance, and more uniform structure, essential for precision industrial applications.
2. What does "60 mesh" specification indicate?: "60 mesh" refers to the particle size grading, where the mica powder passes through a sieve with 60 openings per inch. This corresponds to an approximate particle size below 250 microns, ideal for moderate fineness required in coatings, welding electrodes, and plastic compounding. The mesh size guarantees product consistency and performance.
3. Which standards govern the evaluation of mica powder quality?: Standardized test methods include ASTM D422 for particle sizing, ISO 787 series for chemical properties (LOI, moisture, pH), and EN 1402-9 for silica content determination. These internationally accepted norms ensure consistent product quality and regulatory compliance.
4. How is bulk density significant in technical applications?: Bulk density (measured in g/cm³) affects the material’s packing, flow behavior, and formulation properties. Higher consistency in bulk density ensures predictable dosing for plastics, paints, and welding consumables, impacting mechanical strength and surface finish.
5. Why is calcined mica favored in welding rod manufacturing?: Calcined mica provides electrical insulation, heat resistance, and improved surface smoothness to welding rods. It facilitates proper solidification of the weld bead and prevents electrode sticking, crucial for high-quality, defect-free welds.
6. What is the significance of LOI (Loss on Ignition) in mica powder?: LOI indicates the presence of volatile impurities in mica. Lower LOI (e.g., ≤2.0%) signals minimal organic matter and high product purity, essential for electrical and high-temperature applications.
7. What certifications or compliance can Kehui Mica provide?: Lingshou County Kehui Mica Co., Ltd. can supply REACH-compliant, RoHS-certified, and ISO 9001 managed 60 mesh Calcined Mica Powder, ensuring global environmental and safety standards are met for international buyers.
