Hot Pressed Boron Nitride Ring (BN Ring) Description:

Hot Pressed Boron Nitride (HPBN) Rings are precision-engineered ceramic components made from high-purity hexagonal boron nitride (hBN) through a hot pressing process. This method results in a dense, machinable ceramic with a unique combination of excellent thermal, electrical, and chemical properties.

HPBN rings are characterized by their outstanding thermal stability, non-wettability to molten metals, and excellent electrical insulation performance at high temperatures. They maintain structural integrity in extreme environments, making them ideal for use in high-temperature applications, including vacuum systems, semiconductor processing, and metal handling.
