SECTION 5: PRODUCTION METHODS

Method 1: Grinding and Milling of Natural Graphite

• Process: Natural graphite ore → Crushing → Milling/Grinding → Air classification → Sizing → Graphite powder

• Description: Natural graphite ore is mined, crushed, and milled to fine powder; Classified by particle size; Most common method for natural graphite powder

Method 2: Synthetic Graphite Production (Acheson Process)

• Process: Petroleum coke + Pitch binder → Mixing → Baking (1,000°C) → Graphitization (2,500-3,000°C) → Crushing → Milling → Graphite powder

• Description: Petroleum coke is graphitized in electric resistance furnace at 2,500-3,000°C; Crushed and milled to powder; High-purity synthetic graphite

Method 3: Thermal Purification

• Process: Natural graphite → Heat treatment (2,500-3,000°C) → Purification → Milling → High-purity graphite powder

• Description: Natural graphite is heat-treated at high temperatures to remove impurities; Produces high-purity graphite (≥99.9%)

Method 4: Chemical Purification

• Process: Natural graphite → Acid leaching → Washing → Drying → Milling → Purified graphite powder

• Description: Natural graphite is treated with acids to dissolve impurities; Washed and dried; Produces moderate-purity graphite

SECTION 20: CRITICAL WARNINGS AND BEST PRACTICES

CRITICAL WARNINGS:

• Non-hazardous material but fine dust may cause respiratory tract irritation. Use appropriate dust control measures.

• Non-combustible (bulk). Powder form may be combustible.

• High temperature resistance: Stable up to 3,650°C in inert atmosphere.

• Good electrical and thermal conductivity: Suitable for conductive and heat transfer applications.

• Self-lubricating: Low coefficient of friction; excellent dry lubricant.

• Chemical inertness: Resistant to most chemicals; avoid strong oxidizing agents.

• Incompatibilities: Keep away from strong oxidizing agents and halogens.

• Graphitosis: Prolonged inhalation of graphite dust may cause benign pneumoconiosis (graphitosis).

• Hygiene Requirement: Wash hands thoroughly after handling.

• Dust explosion hazard: Fine graphite powder can form explosive dust-air mixtures.

BEST PRACTICE RECOMMENDATIONS:

• Metallurgy Applications: Use as refractory material and foundry mold lubricant; Provides high-temperature stability; Reduces friction in casting operations.

• Energy / Battery Applications: Use as anode material in lithium-ion batteries; High capacity and long cycle life; Essential for energy storage.

• Lubricant Applications: Use as dry film lubricant; High-temperature lubrication; Anti-seize compounds; Reduces friction and wear.

• Electronics Applications: Use in conductive coatings and antistatic applications; Provides electrical conductivity; EMI shielding.

• Composite Applications: Use as reinforcement in plastics and rubber; Improves mechanical properties; Increases strength and stiffness.

• Handling: Use in well-ventilated areas; Avoid dust generation; Use dust extraction systems; Wear protective gloves, safety goggles, and appropriate respiratory protection.

• Personal Protective Equipment: Safety goggles, protective clothing, protective gloves (nitrile, neoprene), NIOSH-approved dust mask/respirator.

• Hygiene: Wash hands thoroughly after handling; Do not eat, drink, or smoke when using; Remove contaminated clothing and wash before reuse.

• Storage: Store in tightly closed, properly labeled containers in dry conditions; Keep away from oxidizing agents; Moisture-proof containers recommended.

• Spill Response: Avoid dust generation; Use dust extraction systems; Vacuum or wet-sweep; Place in closed containers for disposal; Do not use dry sweeping methods that generate dust.

• Disposal: Dispose of in accordance with local, regional, and national regulations; Graphite is considered non-hazardous waste; Recycle where possible.

SPECIAL NOTE ON DUST EXPLOSION HAZARD:

Graphite powder in fine particulate form can form explosive dust-air mixtures:

• Minimum Ignition Energy: Varies with particle size

• Explosion Limits: Lower explosive limit ~50-100 g/m³

• Prevention: Use explosion-proof equipment; Avoid dust accumulation; Use dust extraction systems; Ground/bond equipment

• Precaution: Keep away from ignition sources; Use inert atmosphere where possible
