摘要
The pyrolysis of the known polymer [-B10H12 center dot Ph2POPPh2](x)- to give a boron-containing ceramic has been studied. The pyrolysis to 1000 degrees 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 temperature up to 2350 degrees C.
