Product variants

Pyrolytic Boron Nitride (PBN) Crucibles are ultra-high-purity ceramic crucibles manufactured by Chemical Vapor Deposition (CVD). With purity levels exceeding 99.99%, PBN crucibles provide exceptional thermal stability, chemical inertness, and contamination-free performance in high-temperature and high-vacuum environments.

Compared with graphite, quartz, and alumina crucibles, PBN crucibles offer superior purity, lower outgassing, and longer service life.

Applications of PBN Crucibles

Semiconductor Crystal Growth

PBN crucibles are widely used for growing:

Gallium Arsenide (GaAs)
Indium Phosphide (InP)
Gallium Phosphide (GaP)

Molecular Beam Epitaxy (MBE)

Ideal for ultra-high vacuum evaporation sources due to extremely low contamination.

OLED Material Evaporation

Suitable for organic material evaporation and deposition systems.

Compound Semiconductor Manufacturing

Used in III-V semiconductor production requiring ultra-high purity processing environments.

High-Temperature Materials Research

Preferred by universities, research laboratories, and national institutes for advanced material synthesis.
