Two boron nitride preceramic polymers were developed: a fusible soluble composition amenable to fiber spinning and an infusible organic solvent-soluble material suitable for preparation of BN coatings, laminating resins, and boron nitride densification. On thermal curing of the preceramic polymers in reactive or inert atmospheres, no boron containing compositions are volatilized indicating a theoretical yield of ceramic. The fully cured materials are colorless and do not undergo weight or shape changes when heated to 1000°C in nitrogen or air. Synthesis of the preceramic polymers, their transformation into boron nitride ceramics, and end item production will be discussed.
