The graphite crucible is a bowl-shaped ceramic with a deep bottom, made by incorporating varying percentages of silicon carbide particles into graphite through isostatic compaction technology. Available with silicon carbide contents of 50%, 24%, and other proportions, it represents a new generation of silicon carbide-enhanced graphite crucibles. Constructed from high-grade refractory materials and formulated specifically for various applications, our crucibles include specialized versions for melting copper, aluminum, zinc oxide, zinc, and tin.
The main raw materials of our graphite crucible are graphite and silicon carbide. The raw materials of graphite and silicon carbide are purchased from domestic sources, mainly large-scale flake graphite purchased from Lanzhou, which has good thermal conductivity and stable quality.
Advantages of graphite crucibles:
1. High temperature resistance:Graphite crucibles can withstand extremely high temperatures, up to 3000°C, and are suitable for high-temperature smelting and heat treatment.
2. Good thermal conductivity:Graphite has excellent thermal conductivity, can quickly and evenly transfer heat, improve heating efficiency and reduce energy consumption.
3. Strong thermal shock resistance: Graphite crucibles are not easy to crack under rapid temperature changes, and are suitable for occasions with frequent heating and cooling.
4. High chemical stability:Graphite has good corrosion resistance to most acids, alkalis and salts, and is suitable for smelting a variety of metals and alloys.
5. High mechanical strength: Graphite crucibles still maintain high mechanical strength at high temperatures and are not easy to deform or damage.
6. Long service life: Graphite crucibles have a long service life and good economic efficiency due to their high temperature resistance, corrosion resistance and high mechanical strength.
7. Easy to process:Graphite materials are easy to process into various shapes and sizes to meet different needs.
8. Environmentally friendly:Graphite crucibles can be reused to reduce waste, and are easy to handle after being discarded, which is environmentally friendly.
