(OLED Used Ceramic Crucibles Produced by Wintrustek)
In the ceramic industries, Pyrolytic Boron Nitride (PBN), Aluminum Nitride (AlN) and 99.8% Aluminium Oxide (Alumina) are used commonly for the OLED industry.
1. Pyrolytic Boron Nitride (PBN) Crucible
PBN crucible is an extremely pure, crystalline type of boron nitride created by chemical vapor deposition (CVD) technology. PBN crucibles offer much higher purity than ordinary boron nitride ceramic.
The CVD technique creates the solid body of the PBN OLED crucible, with all boron nitride crystals growing parallel to the surface on which the vapor is deposited.
PBN products are exceptionally pure because the purity of the gas ingredient can be easily controlled.
With its high density, purity, lack of wetting with organic metals, and extended service life, PBN is becoming a popular material in vacuum operations. The CVD method offers this pyrolytic boron nitride an almost perfect layered structure, resulting in anisotropic thermal conductivity, making it a suitable material for crucibles in the OLED industry. OLED is a developing sophisticated display technology. The PBN OLED crucible serves as the primary container for the evaporation element in the OLED production process.
Pyrolytic Boron Nitride (PBN) OLED Crucible Features:
High purity (99.999%)
Easy cleaning and reusability
Low outgassing at high temperatures
Uniform thickness and good heating consistency
Inert; no reaction with acid or alkali
Superior heat conductivity and stress resistance
2. Aluminum Nitride (AlN) Crucibles
AlN crucibles are ceramic components with superior thermal, mechanical, and electrical qualities. These crucibles have high thermal conductivity, a low dielectric constant, a coefficient of thermal expansion similar to silicon, and excellent electrical insulation. AlN crucibles have a low density and excellent strength, making them non-toxic and long-lasting.
Aluminum nitride (AlN) ceramics have good corrosion resistance and stability at both room and high temperatures. Aluminum nitride crucibles cannot be wetted by copper, aluminum, silver, or other chemicals and are resistant to the dissolution of aluminum, iron, and aluminum alloys, making them suitable containers. Because aluminum nitride is resistant to molten salts like gallium arsenide, utilizing aluminum nitride crucibles instead of glass to manufacture gallium arsenide semiconductors eliminates silicon contamination in the glass, resulting in high-purity gallium arsenide semiconductors.
3. 99.8% Aluminium Oxide (Alumina) Crucible
Under harsh circumstances, the 99.8% alumina crucible provides remarkable mechanical strength, corrosion resistance, and thermal stability. This crucible is used for high-purity melting, calcination, and reaction investigations in a variety of industries, including advanced ceramics, metallurgy, semiconductor production, and chemical processing. It can be used repeatedly without experiencing structural degeneration because of its resistance to corrosive chemicals, aggressive slags, and molten metals.
