Natural Flake Graphite 94–97%

Description

1. Product Overview

This is a high-purity Natural Flake Graphite (94–97% carbon content), precision-milled and classified for demanding industrial applications. It serves as a critical raw material in refractories, lubricants, battery anodes, and advanced thermal management systems. The key value proposition is its exceptional crystallinity, oxidation resistance, and thermal conductivity at a competitive landed cost. Strategically, this grade bridges the gap between mid-tier concentrates and ultra-high-purity synthetics, making it indispensable for global supply chains in energy transition and heavy manufacturing.

2. Key Specifications & Technical Characteristics

• Chemical composition: Carbon (C) 94–97%; Ash ≤ 3–5%; Moisture ≤ 0.5%; Volatile matter ≤ 1.0%

• Purity grade: Industrial premium grade (94%, 95%, 96%, 97% options available)

• Physical form: Natural crystalline flake, silver-black luster

• Particle size distribution: Mesh sizes available: -100, -150, -200, -325 mesh (custom blends on request)

• Typical flake diameter range: 50–500 μm (varies by mesh)

• Density: Bulk density 0.4–0.7 g/cm³ (tapped); true density ~2.25 g/cm³

• Packaging options: 25 kg multi-wall paper bags, 1 MT jumbo bags, or 1,200 kg flexible intermediate bulk containers (FIBC)

• Shelf life: 24 months in dry, covered storage (no degradation if moisture kept below 1%)

3. Core Industrial Applications

• Refractory & metallurgy: As a carbon additive in magnesia-carbon bricks and ladle liners → outperforms amorphous graphite due to higher oxidation onset temperature (650°C vs. 550°C), extending furnace lining life by up to 30%.

• Friction materials: Brake linings and clutch facings → flake morphology improves thermal dissipation and wear resistance, reducing fade under high load compared to synthetic graphite.

• Lubricants & coatings: High-temperature anti-seize compounds and conductive coatings → superior film strength and chemical inertness vs. molybdenum disulfide in oxidizing environments.

• Battery anodes (precursor): For coated spherical purified graphite (CSPG) → 94–97% grade offers lower ash and consistent crystallinity, reducing purification acid consumption by 15–20% versus lower-grade flakes.

• Thermal interface materials (TIMs): In EV power electronics and 5G base stations → flake orientation allows in-plane thermal conductivity > 250 W/m·K, outperforming carbon black and cheaper fillers.

Cost advantage: 30–40% lower priced than 99%+ purified synthetic graphite, with equivalent or better thermal/mechanical performance in non-ultra-pure applications.

4. Competitive Advantages

• Quality consistency: Sourced from single-origin, vertically integrated mines. Each lot tested via LECO carbon analysis, sieve analysis, and XRD crystallinity index (C.I. > 0.92). Certified COA with every shipment.

• Supply reliability: Annual production capacity > 50,000 MT. Safety stock held in three regional warehouses (Asia, Europe, North America). Average lead time: 3 weeks from order to port.

• Logistics capability: Container-ready – no fumigation or special hazmat paperwork (IMO Class 9 not required for flake graphite < 99%).

• Price competitiveness: Direct mine-to-market pricing. Volume discounts scale linearly from 100 MT – no “cliff” pricing.

• Sustainability: Zero child labor, compliant with OECD due diligence guidance. Dry processing (no acid leaching) for 94–96% grades. Scope 3 emissions data available on request.

• Technical support: Full MSDS, TDS, and regulatory compliance packages (REACH, RoHS, TSCA). Application engineering support for blending and sizing optimization.
