Graphite Silicon Carbide Crucible

Graphite silicon carbide crucible is a melting container that combines graphite
and silicon carbide materials, mainly used for melting and casting of non-
ferrous metals. Its basic structure consists of silicon carbide (SiC) and
graphite.
Looking for reliable graphite silicon carbide crucibles for your high-
temperature processes? Our graphite silicon carbide crucibles are engineered to
deliver exceptional performance and durability in demanding industrial
applications.
Advantages
 
1. High temperature resistance: Silicon carbide graphite crucible can work
stably for a long time in a high temperature environment of 1600℃ to 2000℃.
2. Anti-oxidation: Silicon carbide forms a dense SiO₂ protective layer at
high temperature, which effectively prevents oxidation.
3. Corrosion resistance: Adapt to harsh working conditions such as molten
metal and corrosive slag.
4. High thermal conductivity: The high thermal conductivity of graphite
promotes rapid heat conduction and improves smelting efficiency.
5. Long life: The high temperature resistance, anti-oxidation and wear
resistance greatly extend the service life of the crucible.
Applications
1. Metallurgical industry: used in the smelting process of non-ferrous metals
such as aluminum, copper, and magnesium, with high thermal conductivity and
good structural stability.
2. Foundry industry: ensure high-precision casting manufacturing, reduce
energy loss during smelting, and improve production efficiency.
3. Semiconductor industry: shows extremely high purity and temperature
stability in the smelting and crystal pulling of single crystal silicon and
polycrystalline silicon.
