Hot Sale 0.8um Hexagonal Boron Nitride h-BN Lubricant Powder

 Spec: 0.8um, 99.8%, hexagonal, white powder. We could also supply other size, welcome to inquiry.

Application for h-BN powders:

1. Hexagonal BN (h-BN) is the most widely used polymorph.Another advantage of h-BN over graphite is that its lubricity does not require water or gas molecules trapped between the layers. Therefore, h-BN lubricants can be used even in vacuum, e.g. in space applications. The lubricating properties of fine-grained h-BN are used in cosmetics, paints, dental cements, and pencil leads.

2.Because of its excellent thermal and chemical stability, boron nitride ceramics are traditionally used as parts of high-temperature equipment. h-BN can be included in ceramics, alloys, resins, plastics, rubbers, and other materials, giving them self-lubricating properties. 

3.Hexagonal BN is used in xerographic process and laser printers as a charge leakage barrier layer of the photo drum.In the automotive industry, h-BN mixed with a binder (boron oxide) is used for sealing oxygen sensors, which provide feedback for adjusting fuel flow.
