Boron Nitride Sheet

Formula: BN

Form: Foil/Film/Sheet

Material: Boron Nitride

CAS Number: 10043-11-5

Commodity: Ceramics

Boron Nitride sheets is made from van-der-Waals layered crystals, used predominantly for micromechanical exfoliation into 1-atom-thick (quasi-2D) samples. Mechanical exfoliation of the crystals enables the production of materials with atomically thin layers, which encompasses the creation of single-layered 2D materials. With high thermal conductivity and electrical resistivity. Boron nitride sheets are used in applications like microelectronics as a substrate material.
