Graphite crucible with lid
Features
Overview
A graphite crucible with lid is essential for high-temperature melting processes across multiple industries, including metallurgy, foundry, and chemical engineering. Its design, particularly the inclusion of a lid, helps minimize heat loss, reduce oxidation of molten metals, and improve overall efficiency during smelting operations.
Key Features of Graphite Crucibles
| Feature | Benefit |
|---|---|
| Material | High-quality graphite, known for excellent thermal conductivity and high temperature resistance. |
| Lid Design | Prevents contamination and reduces heat loss during melting. |
| Thermal Expansion | Low coefficient of thermal expansion, enabling the crucible to withstand rapid heating and cooling. |
| Chemical Stability | Resistant to corrosion from acid and alkaline solutions, ensuring long-term durability. |
| Versatility | Suitable for melting metals such as gold, silver, copper, aluminum, zinc, and lead. |
