Phosphorus-Containing Derivatives of Decaboranes(14) as Precursors of Boron-Containing Materials
Abstract
Ceramic materials whose properties are attractive for high technology applications often fail to realize their full potential of usefulness due to an inability to be fabricated into complex, durable shapes. One such class of materials is that of the boron-containing ceramics, e.g., boron carbide, boron nitride, boron phosphides, aluminum boride, and boron silicides. We now report the results of an effort to extend the use of preceramic polymers to boron- containing materials. The motivation for this work was to utilize processable materials which give, in general, boron carbide as the major ceramic phase upon pyrolysis. A route to soluble boron-containing polymers has been developed. The synthesis and characterization of phosphorus-containing monomeric and polymeric derivatives of decaborane (B10H14) are given. Preparation and characterization of boron-containing ceramic materials from these molecular and macromolecular species are discussed. Success has been achieved in the areas of ceramic fiber and monolith production and in the area of binder applications for composites of advanced ceramic materials.
