ABSTRACT:
Boron nitride, in its soft or "graphitic" form is utilized as a high-temperature lubricant in an oxidizing atmosphere. A particular application for the lubricant is on or in flexible, ceramic-fiber side seals on a continuous glass coating apparatus and the moving edges of glass itself, thereby minimizing any flow to or from the reactor of gaseous reactants.
