Uses and Characteristics of Graphite Crucibles
Graphite crucibles are known for their excellent thermal conductivity and high-temperature resistance. They have a low coefficient of thermal expansion, which makes them resistant to rapid heating and cooling. Additionally, they have strong corrosion resistance to acidic and alkaline solutions and exhibit excellent chemical stability. These properties make graphite crucibles widely used in metallurgy, casting, machinery, and chemical industries for smelting alloy tool steels and melting non-ferrous metals and their alloys.
Characteristics of Graphite Crucibles
- Excellent Thermal Stability: Graphite crucibles can withstand rapid temperature changes, offering good resistance to thermal shock.
- Corrosion and Impact Resistance: They have strong resistance to corrosion and mechanical impact, ensuring the reliability and quality of the product.
- Special Glaze Coating: The exterior is coated with a special glaze and made from dense forming materials, which enhances corrosion resistance and extends the product’s lifespan.
- Superior Thermal Conductivity: The excellent thermal conductivity shortens the melting time and saves energy.
Note: After heating, graphite crucibles should not be immediately placed on a cold metal surface to avoid cracking due to rapid cooling.
