Boron-Nitride Preceramic Polymer Studies

Abstract

Boron nitride fibers and boron nitride coatings on alumina fibers are described. The boron nitride fibers were obtained from fusible preceramic polymer. For the coatings, a non-fusible, organic solvent soluble, preceramic polymer was utilized. Transformation of the preceramic polymers to boron nitride ceramic was accomplished in an ammonia atmosphere. The fully cured ceramics are colorless and do not undergo weight or shape changes when heated to 1000 C in nitrogen or air.
