Boron Nitride Coating High Temperature

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.

Boron nitride coating high temperature.

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. Boron nitride light leakage proof coating was prepared via chemical vapor deposition cvd process on silica optical fiber for sensing applications at high temperatures. Combat boron nitride powders and aqueous coatings offer a solution for this challenge. Molten aluminum rolls off it like water on a duck s back.

Improving the operating life and performance consistency of metal plastic and refractory parts at high temperatures is challenge faced by many industries. They are non wetting to molten metal and act like a high temperature version of teflon providing these qualities. Compared with the original fiber the tensile strength of bn coated fiber was more than two times higher at both room temperature and 700 c. 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.

The high chemical purity of bn particles along with an inorganic binder result in a very superior formulation which delivers a fluid and continuous coating with excellent adhesion to the surface. High temperature lubrication and mold release.
