Manufacturing Process: Flake Graphite Powder
Manufacturing graphite powder for sale requires precise control of crystallinity, purity, and granulation. Below is a graphical illustration of the process, followed by detailed steps.
- Raw Ore Selection: Premium graphite ore (min. fixed carbon 85%) sourced from natural mines is inspected under ISO 9001 protocols.
- Grinding and Flake Liberation: Ore is milled using ball mills and hammer crushers to release graphite flakes without breaking their crystalline structure.
- Flotation: Advanced flotation cells separate graphite from the gangue minerals, enhancing final fixed carbon to 93–98%.
- Purification (Chemical/Physical): Achieve ultra-high purity (≥99.5%) for battery-grade flake graphite powder through alkali/acid leaching, under RoHS-compliant, low-emission processes.
- Drying & Classifying: Controlled drying at <90°C preserves layer integrity; subsequent sieving ensures precise granularity (D50: 15–500μm).
- Quality Control: Each lot undergoes elemental analysis (XRF, AAS), particle size measurement by laser diffraction, and performance benchmarking (conductivity, lubricity, thermal stability).
- Packing: Customized multi-layer moisture-resistant bags (25kg/1000kg) to maintain shelf life up to 36 months.

FAQ: Technical Questions & Purchase Guidance
- 1. What is the difference between flake graphite powder and synthetic graphite powder?
- Flake graphite powder is naturally occurring with a layered, hexagonal microstructure, delivering superior lubricity and higher natural purity. Synthetic graphite powder is man-made, typically showing higher electrical conductivity but often more costly and less eco-friendly due to energy-intensive production.
- 2. What are key product specifications to consider when choosing graphene powder?
- Pay close attention to fixed carbon content (higher means better conductivity), ash content (lower is preferable), particle size (depends on application), moisture, and industry-required certifications such as ISO 9001 and RoHS.
- 3. Can GloryStar Export provide custom particle size distribution or surface treatment?
- Yes, both micro and macro granularity (D50 from 15μm to 500μm) are available, and custom acid/alkali surface treatments for hydrophilicity/oleophilicity can be developed per project.
- 4. What is the recommended storage condition for battery-grade graphite powder?
- Store in sealed, moisture-proof packaging at room temperature (≤25°C, <55%RH). Opened bags should be used within 72 hours to maintain graphite powder for sale's performance.
- 5. Which standards/certifications does the product meet?
- Complies with ISO 9001:2015 (quality management), RoHS, REACH, and passes required GB/T 24533, ASTM D3849 tests. Third-party SGS or Intertek reports available upon request.
