Introduction to Pyrolytic Boron Nitride (PBN)

Pyrolytic Boron Nitride, abbreviated as Pyrolytic BN or PBN, also known as Chemical vapour-deposited Boron Nitride, Chemical Vapour-deposition of Boron Nitride or CVD-BN, etc. As the name suggests, this is a kind of boron nitride prepared by high temperature pyrolysis reaction by chemical vapor deposition method. Speaking of boron nitride, we must first talk about […]

Magnetic characteristics of permanent magnetic materials

Magnetism is the basic property of matter as well as force, heat, electricity and light. Materials with ferromagnetism are usually called magnetic materials. The biggest characteristic of magnetic materials is the hysteresis behavior, that is, the magnetization M changes with the external magnetic field. When H returns from a certain state to zero, M still […]
