Product Overview
Graphite tanks are high-temperature and corrosion-resistant containers made from high-purity graphite materials. They are widely used in industries such as chemical processing, metallurgy, semiconductors, and new energy. Thanks to graphite's excellent thermal conductivity, chemical stability, and high-temperature strength, graphite tanks are the ideal choice for handling highly corrosive media, molten salts, and special gas environments.
Key Features
✅ Extreme Temperature Resistance:
Long-term use up to 3000°C in inert atmospheres; 500°C in oxidizing environments (with coating).
✅ Chemical Corrosion Resistance:
Resistant to strong acids (e.g., sulfuric acid, hydrochloric acid), alkalis, and organic solvents.
✅ High Thermal Conductivity:
Ensures rapid and uniform heat transfer, ideal for high-temperature synthesis and crystal growth processes.
✅ Lightweight Design:
Density only 1/5 that of metal, reducing equipment load.
✅ Customization Services:
Tailored solutions for dimensions, structures, coatings, and more.
