Product Description

Pyrolytic Boron Nitride VGF Crucible High-Purity PBN Crucible for GaAs / InP Single Crystal Growth

Description

Pyrolytic Boron Nitride VGF Crucibles are ultra-high purity CVD PBN crucibles engineered for Vertical

Gradient Freeze (VGF) growth of GaAs, InP and other compound semiconductors.

Their dense, non-porous structure, low outgassing and excellent thermal stability ensure stable crystal growth,

low contamination and consistent ingot quality in advanced semiconductor and optoelectronic applications.

Plasma corrosion ruining your crucibles and disrupting production?

Our PBN Ceramic Crucible features a dense, high-purity structure that effectively resists plasma corrosion.

Designed for plasma processing applications in electronics and semiconductor industries,

it minimizes wear and tear, extends service life, and ensures stable process output.

Protect your operations from plasma damage—trust our PBN Ceramic Crucible for superior corrosion resistance.

PBN Ceramic Applications:

- Crystal growth (VGF, LEC Crucible)

- Molecular Beam Epitaxy(MBE) Crucible

- MOCVD Heater

- PBN Infrared Window

- Traveling Wave Tube (TWT) (PBN Support Rod)

- PBN Coating Graphite

- High temperature, vacuum equipment insulator

Product Features :

> High purity (99.999%) > Low outgassing in high temperature >Uniform thickness, Good consistency in heating 
> Excellent thermal conductivity and shock resistance
> Easy cleaning and Reusabilit
> Inert, no reaction with acid and alkali
