Graphite Crucible

Product Overview

Graphite crucibles are made from high-purity crystalline natural graphite combined with refractory clay. They are widely used in high-temperature melting and chemical reactions. With excellent resistance to high temperatures, corrosion, and good chemical stability, graphite crucibles are particularly suitable for melting precious metals and special alloy steels. Available in different variations such as pure graphite, clay graphite, and silicon carbide graphite, they serve a wide range of applications.

Key Features

• Excellent Thermal Stability: Low thermal expansion coefficient, providing good strain resistance and the ability to withstand rapid heating and cooling.
• Corrosion and Impact Resistance: Ensures long service life even in high-temperature environments.
• Chemical Stability: Resistant to strong acids and alkalis, unaffected by chemical reactions.
• Good Thermal Conductivity: Effectively reduces melting time and saves energy.
• High Purity: Pure graphite crucibles have ash content below 300pp, ensuring no contamination of precious metals during melting.

Applications

• Metallurgical Industry: Widely used for melting metals, special alloy steels, and precious metals.
• Casting Industry: Used for casting non-ferrous metals and their alloys.
• Chemical Industry: Suitable for high-temperature melting and as reaction vessels in chemical processes.
• Machinery Industry: Commonly used for melting and material processing at high temperatures.
