Pyrolytic Boron Nitride OLED Crucible, PBN Ceramic OLED Crucibles

The evaporation unit is an important component of OLED production equipment. The support frame and crucible are the main components of the evaporation unit. The support frame needs to have high insulation and characteristics such as not being easy to deform at high temperatures and not releasing gas, while the crucible needs to have high purity, no wetting with organic metals, and long service life. The Pyrolytic Boron Nitride Ring and Pyrolytic Boron Nitride OLED Crucible series are the corresponding products produced and developed in line with the development of this technology and have been reliably used in many OLED production lines.

OLED crucible is a type of PBN crucible used in OLED and CIGS evaporation technology. It is widely used in metal and semiconductor evaporation for its ultra-high purity, chemical inertness, excellent high-temperature resistance, and high-temperature stability.

PBN crucible characteristics

PBN OLED crucible is widely used in metal and semiconductor evaporation due to its ultra-high purity, chemical inertness, excellent high-temperature resistance, and high-temperature stability.
-High purity (>99.99%)
-No gas release at high temperature
-Uniform thickness, good heating consistency
-Excellent thermal conductivity and thermal shock resistance
-Chemically inert, no reaction with acids, alkalis, salts, and organic solvents at high temperature

Packing

As a ceramic material, boron nitride is quite fragile in a lot of cases. The Pyrolytic Boron Nitride OLED crucibles are usually held in plastic bags by vacuum, and protected with heavy foam.
