PRODUCTION OF HOMOGENEOUS COMPOSITE PRESS-POWDERS BASED ON ZRB2 AND SIC FOR UHTCS

Abstract

The aim of the research was to obtain superfine homogeneous composite powders, which, due to their unique composition and morphology, will be used to obtain ceramics with improved properties for the thermal protection of supersonic aircraft. The novelty of research was microstructure refining methods, selection of sintering additives/dopants and their combining action. As regards sintering additives and dopants, B4C and graphite powder, carbon black and graphene structures were used. The use of the latter individually and in combination sintering additives was one of the innovations of the research.
