Boron Nitride Coating On Graphite

Graphite and hexagonal boron nitride h bn are two prominent members of the family of layered materials possessing a hexagonal lattice structure while graphite has nonpolar homonuclear c c intralayer bonds h bn presents highly polar b n bonds resulting in different optimal stacking modes of the two materials in the bulk form furthermore the static polarizabilities of the constituent.

Boron nitride coating on graphite.

Boron nitride is a ceramic compound which is chemically inert and stable between medium and high temperatures resistant up to 1000 c in air 1400 c in vacuum and 1800 c in inert gas atmosphere. Boron nitride and graphite are important crystalline materials. Boron nitride aqueous coatings for high temperature protection lubrication and release. Supplied in a liquid form suitable for brushing they can be diluted with water to spraying and dipping consistencies and applied to a variety of porous and non porous materials including ceramics metals graphite.

Ceraglide boron nitride bn coatings are composed of a high purity bn powder base paired with a high temperature bond phase. Our bn coating is an excellent release agent and well suited to protect the surface of graphite parts from oxidation and to create a non wetting. Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula bn it exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. They are non wetting to molten metal and act like a high temperature version of teflon providing these qualities.

Hbn is able to withstand temperatures up to 3 300 degrees f under normal atmospheric conditions before. Ceraglide boron nitride bn coatings are composed of a high purity. Molten aluminum rolls off it like water on a duck s back. Resistant to and non wet by most molten metals slags and drosses ceraglide bn coatings can be used up to 1372 c 2500 f in a reducing.

The hexagonal form corresponding to graphite is the most stable and soft among bn polymorphs and is therefore used as a lubricant and an additive to cosmetic products. Boron nitride powder coatings a highly versatile synthetic material with similar thermal conductivity and lubricating properties as graphite hexagonal boron nitride hbn is the crystalline powder often referred to as white graphite. Our main coatings are made with boron nitride. They have different atomic compositions which results in different chemical and physical properties.

The key difference between boron nitride and graphite is that boron nitride is composed of boron and nitrogen atoms whereas graphite is composed of carbon atoms.
