Boron Nitride Tube Description

Boron nitride (BN) is a compound composed of equal numbers of boron and nitrogen atoms, known for its unique properties. The most common form, hexagonal boron nitride (HBN), often referred to as "white graphite," is the softest and most stable of the BN polymorphs. It serves as an effective lubricant and a valuable additive in cosmetic products. The cubic form (CBN), analogous to diamond, is renowned for its exceptional hardness, second only to diamond itself. There is also a rare form, wurtzite BN (WBN), which is structurally similar to lonsdaleite and may surpass CBN in hardness.

Boron Nitride tubes are versatile components that can be joined together using flat or threaded joints to create longer tubes, tailored to specific application needs.
