PBN can be heated to 2300°C under ultra-high vacuum without decomposition, has high purity, more than 99.99%, does not release gas impurities and other excellent characteristics at high temperatures, these characteristics make PBN can be processed into different shapes.
Pyrolytic Boron Nitride (PBN) is frequently used to make filament rings to hold Ta wire in MBE equipment, due to its high working temperature and vacuum property. INNOVACERA can be customized according to the size, and Filament Rings are usually held in plastic bags by vacuum, and protected with heavy foam.
