Boron Nitride Blank (BN Blank) Description
Hot Pressed Boron Nitride Blanks are solid, machinable ceramic components made from hexagonal boron nitride (hBN) through a high-temperature hot pressing process. This method compacts the material under heat and pressure to achieve high density and enhanced mechanical strength without compromising the unique properties of hBN.
