Momentive Performance Materials BNC1 Boron Nitride (BN) Refractory Composite

Boron Nitride is a unique engineering material. It is a soft, machinable ceramic which can be combined with other refractory ceramics including Aluminum Oxide, Silicon Nitride, Aluminum Nitride, Mullite and Titanium Diboride. This results in composites which are machinable, thermal shock resistant, and chemically compatible in a wide range of environments. In combination with Titanium Diboride, for example, BN can be used as a heating source for the aluminum metallization of films and papers. BN composites are also used as break-rings in the horizontal continuous castings of steel and nozzles in rapid solidification processes. Other composite applications include the following: High temperature refractory shapesGlass forming tools and refractoriesMolds, dies and refractories for metalformingFurnace vents, stacks and fixturesGrades BNC 1 & 2 offer excellent corrosion and wear resistance, have excellent thermal shock capability and low CTE, are non-wetting and are self lubricating.Information provided by Momentive Performance Materials, formerly GE Advanced Ceramics.
