GA Boron Nitride Crucible， BN & PBN
High-Purity Boron Nitride Crucibles in PVD process
Purity Requirements:
Boron Nitride Crucibles are typically made from high-purity boron nitride with a purity of 99.7% to ensure the cleanliness and stability of the melt inside the crucible.
Intruduction to Conductive Boron Nitride Crucible:
Boron nitride ceramics are known for their exceptional insulating properties and high resistivity. However, conductive boron nitride (c-BN) crucibles have been specially engineered to facilitate more uniform and controlled heating, addressing the needs of evaporation processes where conductivity is essential.
Intruduction to PBN Crucible:
The full name of PBN crucibles is Pyrolytic Boron Nitride. Due to the use of vapor deposition for manufacturing, PBN crucibles offer exceptionally high purity, making them ideal for producing high-performance materials, such as the growth of gallium nitride (GaN) crystals for semiconductor applications.
Main Applications of Boron Nitride Crucible (BN Crucible)
1.Metal Evaporation Source Crucible
Boron Nitride Crucible (BN Crucible) is widely used as a metal evaporation source in the PVD (Physical Vapor Deposition) process. In this process, metals or other materials are evaporated into a gaseous state and then deposited onto a substrate, forming a thin film layer.
2.Semiconductor Material Growth
BN Crucibles are also used in the growth of certain semiconductor materials, particularly when high-temperature stability and precise control of the melt are required. The excellent thermal stability and corrosion resistance of boron nitride make it an ideal choice for these applications.
3.Processing of Optical and Electronic Materials
Boron Nitride Crucible (BN Crucible) is extensively used in the melting and processing of optical and electronic materials, where high-temperature control and clean processing are critical.
Advantages of Boron Nitride Crucible (BN Crucible)
1.High-Temperature Chemical Stability and Corrosion Resistance
Boron Nitride Crucibles offer exceptional high-temperature chemical stability and corrosion resistance, allowing them to withstand the high temperatures and chemical reactions involved in metal evaporation and PVD deposition processes, ensuring material purity and stability.
2.Prevention of Oxygen Contamination
Since BN Crucibles are made of nitrided material, they effectively prevent oxygen contamination, which can occur when using oxide crucibles at high temperatures. This ensures the purity of the melt and efficient material processing.
