GRAPHITIZATION CRUCIBLE
Application Fields: Graphitization crucibles are large containers made of high-purity graphite materials, widely used in high-temperature smelting, metal casting, crystal growth, chemical synthesis and other fields. Temperature Resistance: 3000°C Product Features: - High Temperature Resistance: Graphite can withstand temperatures above 3000°C in an inert atmosphere; in an oxidizing environment, it requires a protective coating (usually used up to about 500-800°C).
- Excellent Thermal Conductivity: High thermal conductivity coefficient enables fast and uniform heat transfer.
- Chemical Stability: Resistant to acid and alkali corrosion (except strong oxidizing acids), suitable for melting active metals (such as lithium, aluminum, copper, etc.).
- Low Thermal Expansion Coefficient: Good thermal shock resistance, capable of withstanding drastic temperature changes.
