Pyrolytic Boron Nitride OLED Crucible

Pyrolytic Boron Nitride (PBN) is a kind of advanced ceramic, and it can be produced with 99.99% purity in high density. It is made by ammonia and boron halide through chemical vapor deposition (CVD) process in high temperature and high vacuum condition: NH₃ + BX₃ = BN + 3HX.

The deposition process of PBN is like falling snow: the hexagonal primary boron nitride falls on graphite matrix material, and finally cooled and demolded after reaching a certain thickness. It can be produced as PBN sheets, and also can be produced as PBN final products like crucibles, boats, coating, etc.

Pyrolytic Boron Nitride (PBN) Typical Applications:

Crucible and base for synthesis of semiconductor single crystal and III-V compounds
LEC series crucible for in situ synthesis of GaAs, InP and gap single crystals.
MBE series crucible for molecular beam extension
Crucible, VGF series
PBN / PG composite heater coating
Graphite heater insulation coating
High temperature insulating fluid nozzle
MOCVD insulation board
Special shaped crucible and special shaped graphite coating
Composite heater for wafer annealing process

OLED is a kind of new developing advanced display technology. The PBN OLED Crucible is applied as the main vessel of the OLED effusion cell.

Features of the PBN OLED Crucible:

High purity (99.99%)Low outgassing in high temperature
Uniform thickness, good consistency in heating
Excellent thermal conductivity and shock resistance
Easy cleaning and reusability
Inert, no reaction with acid or alkali
