BZN Carbon supplies custom-engineered carbon carbon composite crucibles designed for extreme temperature applications. Manufactured with advanced carbon fiber reinforcement techniques such as 2.5D, 3D, and 4D structures, our CFC crucibles deliver superior thermal stability, durability, and cost-efficiency compared to conventional graphite crucibles.

These crucibles are especially suited for processes requiring minimal contamination, extended service life, and high mechanical strength at elevated temperatures.

What Is a Carbon Carbon Composite Crucible?
A carbon carbon composite crucible is made from carbon fibers embedded in a carbon matrix, typically reinforced in multiple directions (2.5D, 3D, 4D) to improve strength and longevity. These crucibles are engineered for use in environments exceeding 2000°C, where traditional ceramics or graphite may fail.

Applications
BZN Carbon’s crucibles are ideal for:

High-temperature vacuum or inert gas environments
Crystal growth (such as Czochralski and Bridgman methods)
Semiconductor and photovoltaic silicon processing
Metal smelting and sintering
Furnace linings and advanced ceramic firing
Research institutions and aerospace material testing

Why Choose BZN Carbon Crucibles?

Exceptional thermal shock resistance
Extended service life under extreme temperatures
Excellent resistance to chemical erosion
Low thermal expansion and high thermal conductivity
Significantly lower ash and impurity levels
