Boron Nitride

Boron Nitride solid components for refractory, insulation, kiln furniture and molten metal
Available in variety of grades, Combat® Boron Nitride Solids are a wise choice for applications where electrical isolation, thermal shock resistance, corrosion resistance, refractoriness, inertness or high thermal conductivity is important. These features enable a variety of applications in high-temperature manufacturing space. Some of the examples are -


• High temperature electrical insulators and vacuum furnace supports which require electrical resistivity, high temperature strength, thermal shock resistance and low chemical reactivity
• Crucibles and containers for high purity molten metals
• Insulators and source fixtures for ion implantation systems which require high temperature purity and electrical insulation
• Radar components and antenna windows which require exacting electrical and thermal properties
• Setterplates for the processing of other advanced materials which require stable, inert surfaces
• Nozzles for powdered metal spraying


 


Boron Nitride aqueous coatings for high temperature mold release and protection
Combat® Boron Nitride Coatings are entirely inorganic, composed of boron nitride powder and a high temperature bond phase. Supplied in a liquid form, these coatings can be applied by brushing, spraying or dipping to a variety of porous and non-porous materials including graphite, metals, ceramics and organics.
Boron Nitride coatings offer excellent lubrication, mold release and surface protection in light metal processing, secondary aluminum processing and glass manufacturing in processes such as hot pressing, forging, extrusion, Coating of launders, troughs, ladles, spoons, sieves, cups etc. and super-plastic and quick-plastic forging.


Combat Boron Nitride Coatings can be used up to 1372°C (2500°F) in a reducing/inert atmosphere and 850°C (1562°F) in an oxidizing atmosphere, and will retain many of the properties of Boron Nitride such as


• Ready to use, water based, completely inorganic coatings for easy application
• Excellent parting plane and lubricity provide outstanding release properties even at high temperatures
• Non-wet by most molten metals, salts, fluxes enables extreme resistant to molten metal corrosion and light metal drosses
• Increases corrosion resistance and lifetime of graphite and non-oxide refractory components and tools
• Viable in green tint, visible on white refractory for easy detection of reapplication


Melting and Holding Furnace, Crucibles


Combat® Solid Boron Nitride, a truly machinable advanced ceramic from Saint Gobain solves problems that could not possibly be tackled with other compositions.
Combat® Boron Nitride Solids fight off temperatures over 2000°C and, depending on the grade, carries a dielectric strength of nearly 1000 volts/mil. Combat Boron Nitride Solids can easily be machined into crucibles, rods, bars, plates and even custom intricate shapes. The exceptional characteristics make it ideal for fixture or jig materials for sealing or brazing operations in induction, vacuum and atmosphere furnaces, for molten metal crucibles, heat sinks and high temperature insulators.

Casting machines and Pouring Equipments, Peripheral equipment and auxiliary material, release agents for die-casting


Combat Boron Nitride coatings are entirely inorganic, composed of Boron Nitride powder and a high-temperature bond phase.


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 graphite, metals and ceramics.
With its unique combination of physical and chemical properties, Combat boron nitride when used as a release agent for aluminum extrusion, offers many advantages over graphite or carbon black:
• Low coefficient of friction – soft, lubricious and non-abrading even at higher temperatures
• Minimizes surface defects as unlike Carbon black, boron nitride does leaves less visible or even non-visible any marks in the profile
• High temperature resistance – up to 900°C in air, 2000°C in inert atmosphere
• White, clean appearance
• Corrosion resistant and non-wet by most molten metals
• Inert, non-flammable, non-toxic – safe to store and handle
• Electrically insulating - reduces risks of short-circuit in electrical installations
• Reduces release agent consumption from every cycle ( as is the case with both carbon soot and graphite) to every third to fifth pressing cycle
