摘要： The present invention lies in the fields of chemistry and materials engineering. More specifically, the present invention describes a process of heat treatment of polymeric precursors including as active phases particle charge or a mixture of active phases with inert phases called “fillers”. It is also described a surface including ceramic polymer obtained by said process. The volumetric positive variation resulting from the formation of new phases, which for their formation, incorporate atoms from the gaseous phase, contributes to a minor shrinkage of the composition during the heat treatment process. The process of the present invention allows obtaining the desired phases in smaller treatment times and lower temperatures, when compared to a thermal treatment process as conventional pyrolysis (PC) due to the presence of highly reactive species, as for example atomic nitrogen produced by the dissociation of nitrogen molecules in the plasma environment.
