Preparation of Boron-Containing Ceramic Materials by Pyrolysis of the Decaborane(14)-Derived (-B10H12.Ph2POPPh2)(x)-Polymer

摘要

The pyrolysis of the known polymer -B10H12. Ph2POPPh2x- to give a boron-containing ceramic has been studied. The pyrolysis to 1000 C gives an amorphous solid in 93% ceramic yield that contains boron, phosphorus, oxygen, and a large excess of carbon. Further studies devoted to this material have served to characterize it with respect to surface area, pore size and distribution, density, grain size, crystalline phases, and elemental composition as a function of the temperature up 2350 C.
