“…Monteverde et al [66] have performed extensive research using hot pressing and various sintering aids. A monolithic ZrB 2 ceramic was compared with ZrB 2 -TiB 2 and ZrB 2 -B 4 C composites, and it was concluded that the composite materials had better mechanical properties and performed better in long-term furnace oxidation tests.…”

The objective of this paper is to describe the current state of the art of the research on Ultra High Temperature Ceramic materials with particular reference to their space applications, and also to report on the activities performed on UHTC in the past decade by the Italian Aerospace Research Centre in the specific technological field of structural thermal protection systems. Within several internal research project, various UHTC composition, mainly based upon Zirconium Diboride and Hafnium Diboride with added secondary phases and sintering aid were examined characterized in their mechanical properties and oxidation resistance. Two main composition were selected as the most promising for hot structure manufacturing: these materials were extensively characterized in order to obtain a comprehensive database of properties to feed the thermomechanical design of prototype hot structures. Technological demonstrators were manufactured by hot pressing followed by further fine machining with Electrical Discharge methods, and then tested at high temperature for long times in a plasma torch facility. The main outstanding results obtained are discussed in this paper. Future outlooks related to the UHTC technology and its further development are also provided.

“…With at least 27 known diborides, this can allow for a multitude of combinations of properties [55]. If composites of these materials are desired for strengthening, some combinations have smaller solubility ranges and/or sluggish solutionizing rates that can be exploited to produce spinodal decomposition microstructures and multi-phase ceramics [54,[61][62].…”
