【 摘 要 】

The influence of heat treatment in vacuum and in oxygen on the composition and distribution of tantalum containing nanocomposites in silicon-carbon matrix has been investigated. It is shown that the influence of heat treatment determines the interaction of oxygen with the atoms in the amorphous matrix as well as with nanocrystals of tantalum carbide. We propose a qualitative model of the processes occurring in these interactions.
