Fundamental Phase Characteristics Graphite exhibits atypical phase transition behavior distinct from conventional materials: Sublimation Point: 3,600°C (6,512°F) at standard pressure Melting Phenomenon: Only occurs under extreme pressure (>100 atm) Triple Point: 100 atm / 4,500 K (theoretical) Graphite Phase Diagram: Pressure vs Temperature Structural Determinants of Thermal Stability Crystalline Architecture Intralayer Bonding: sp² hybridized covalent

1. Friction Reduction Mechanism Coefficient of Friction: 0.08-0.15 (ASTM D2714) Operational Impact: 40-60% reduction in mechanical wear 15-30 dB noise attenuation Thermal load reduction by 35-50% Mechanism: Lamellar carbon structure enables interlayer slippage under shear stress 2. Extreme Condition Performance Environment Competency Limitation High Temp Stable to 450°C (air) / 3000°C (inert) Oxidizes >450°C in

Material Fundamentals Graphite powder is a finely divided carbonaceous material characterized by its dark hue and exceptional physicochemical properties. With carbon content typically exceeding 99%, this material exhibits: Thermal conductivity: 100-400 W/(m·K) Electrical resistivity: 10⁻⁵–10⁻³ Ω·m Chemical inertness across pH 0-14 environments Industrial Production Process Stage 1: Mineral Extraction Underground mining operations targeting graphite-bearing metamorphic

Intrinsic Thermal Conductivity Graphite exhibits exceptional heat transfer capabilities among carbon allotropes, with in-plane thermal conductivity reaching 1500-2000 W/(m·K)—significantly surpassing copper (~400 W/(m·K)). This originates from: Delocalized π-electron system via sp² hybridization Rigid lattice structure with strong covalent bonds Phonon-dominated heat transfer mechanism (~4300 W/(m·K) at room temperature) Key Thermophysical Parameters Property Value Range Physical
