High-Performance Graphite Accessories
High-purity graphite products made from premium flake or isostatic graphite, with carbon content ≥99.9% (up to 99.999%). Features ultra-low ash, excellent heat resistance (up to 3000°C in inert/vacuum), superior conductivity, and strong chemical stability. Ideal for metallurgy, semiconductors, new energy batteries, photovoltaics, lab research, and vacuum furnaces.
Product Features
- Ultra-High Purity: Ash ≤200 ppm (customizable to ≤50 ppm or lower), prevents sample/melt contamination
- Exceptional High-Temperature Resistance: Up to 2800–3000°C in vacuum/inert; stable at 1000–1800°C in air
- Excellent Electrical & Thermal Conductivity: Low resistivity, high thermal conductivity, uniform heating, energy-efficient

FAQ
Q1: Can graphite products be used long-term in air at high temperatures?
A: Recommended max 1000–1800°C in air (depending on grade/coating). Use vacuum or inert gas for higher temperatures to avoid oxidation.
Q2: How to choose the right specifications?
A: Match to temperature, atmosphere, size/load, and purity needs. Share your application — we’ll recommend the best option for free.
Q3: How to clean and store after use?
A: Cool, brush off residues gently, avoid impact. Lightly polish oxidized areas if needed. Store dry and protected from sudden temperature changes.
