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

Core Pricing Characteristics As a non-futures traded commodity, graphite exhibits unique pricing attributes: Bilateral Negotiation Mechanism: >80% transactions priced through direct buyer-seller negotiations Market Transparency Limitations: Absence of unified exchange quotation systems Volume Discount Effect: Bulk procurement prices 30-50% lower than retail Price Determinants Matrix Factor Price Fluctuation Range Case Study Form & Specification $500-9,800/t

Material Composition and Characteristics Carbon graphite is a synthetic composite material formed by combining an amorphous carbon matrix with flake graphite, exhibiting a steel-gray to deep black gradient. Its core properties derive from a unique dual-phase structure: Property Category Performance Specifications Mechanism Thermal Stability Oxidative (200-600°C) Inert (≤3000°C) Cryogenic (-270°C) Stability of sp²-hybridized carbon network

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
