Morgan advanced materials technical ceramics business pyrolytic boron nitride pbn coated graphite components are the best choice to extend heater life or temperature capability in mbe and cigs pv applications.
Boron nitride coating on graphite.
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.
They have different atomic compositions which results in different chemical and physical properties.
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.
Our main coatings are made with boron nitride.
They are non wetting to molten metal and act like a high temperature version of teflon providing these qualities.
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.
Hexagonal boron nitride hbn is a ceramic that has all of the advantages of graphite as a lubricant with none of the disadvantages.
Belted bullets and crush rib sabots with white boron nitride coating before right and after left coating.
Molten aluminum rolls off it like water on a duck s back.
Hbn is able to withstand temperatures up to 3 300 degrees f under normal atmospheric conditions before.
Boron nitride and graphite are important crystalline materials.
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.
Ceraglide boron nitride bn coatings are composed of a high purity.
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.
Boron nitride aqueous coatings for high temperature protection lubrication and release.
Ceraglide boron nitride bn coatings are composed of a high purity bn powder base paired with a high temperature bond phase.
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.
