Abstract
Using EXAES and X-ray RED methods the phase composition of polycarbosylanes containing zirconium has been investigated. It has been demonstrated that metal complex decomposes with introduction into polycarbosylane and formati on of metal nanoparticles with the size not exceeding 2 nm and modification of the matrix structure occur. Interaction of the introduced metal with ma trix occurs during calcination of sample at 1373-1473 K in nitrogen with fo rming of zirconium silicide. (C) 2000 Elsevier Science B.V.
