摘要：

Hexagonal boron nitride (h-BN) ceramics can be prepared from polymeric precursors by heat treatment under inert atmosphere. The purpose of this paper is to illustrate the strategy that can be followed to characterize by N-15 and B-11 solid state NMR the polymers as well as their pyrolysis derivatives. A suitable choice of NMR techniques, combined with isotopic enrichment, can lead to a good qualitative as well as quantitative description of the local environment of B and N sites in such complex samples.
