Combat® BN Industrial Powders Combat Boron Nitride Industrial Powders | Saint-Gobain

Combat® Industrial Boron Nitride powders are pure, white, ceramic materials with a hexagonal crystal structure similar to graphite. Commonly known as "white graphite," hexagonal BN (hBN) is a synthetic ceramic produced by reacting Boron source and a Nitrogen source at temperatures above 1600°C. The resulting product is a lubricious white powder that has excellent high-temperature stability (oxidation resistant up to 900°C) and lubricating properties. 

A non-toxic white (clean appearance), and a non-conductor of electricity, boron Nitride offers an excellent substitute for other commonly used powder lubricants in a variety of industrial applications such as graphite, molybdenum disulfide, and organic waxes and oils. In most cases, boron nitride substantially improves the efficiency of these applications. 

  • Non-wet by molten metals
  • Chemically inert and corrosion resistant
  • Lubricious at temperatures up to 1800°C in inert atmospheres
  • Excellent high temperature stability and oxidation resistant in air up to 900ºC
  • High thermal conductivity for efficient heat dissipation from components
  • Non-toxic, safe for human contact and the environment
  • White, clean appearance
  • Improved alternative to solid lubricants such as graphite and molybdenum disulphide
Combat® Boron Nitride Industrial powders are available in a wide variety of grades and particle morphologies. The key features required for the numerous and varied applications are high temperature stability and lubricity.  
 
Platelet grades are single crystal particles, available in D50 of 1 to 30 microns. Agglomerates are coarse (-40 mesh) powders made of many platelets put together in a random orientation, and are available in high density and low density grades.  Additionally, we offer customization to customer requested properties.
