“…a SiC polytypic transformation. MoSi 2 was selected as sintering aid in view of its role in favoring the densification through formation of transient liquid phases and of its refractoriness at high temperature [5,11]. Little amount of liquid phases formed at 2010°C, owing to the eutectic between MoSi 2 and SiC [16], certainly helped the local rearrangement and agglomeration of SiC rounded particles and favored their evolution to platelets leaving clean grain boundaries with the matrix.…”

Ultra-high temperature ceramics (UHTCs) have emerged as promising materials for high-temperature aerospace applications due to their high melting temperature and superior ablation performance. Even still, they have yet to reach their full potential due to the catastrophic brittle failure that typically accompanies the intrinsic low fracture toughness of ceramic materials. Therefore, the emerging field of UHTC ceramic matrix composites (UHTCMCs) offers the toughness benefits of a composite with the high temperature stability of UHTCs. Here, we outline work in the last decade on the processing of UHTCs with a reinforcing fiber phase for enhanced fracture toughness. Included are fibers of both carbon and silicon carbide composition in both continuous and chopped fiber lengths. Particular emphasis is given to emerging research from the last few years to highlight novel developments.

Ultra-high temperature ceramics developments for hypersonic applications

et al. 2020

Ultra-High Temperature Ceramics (UHTC) are good candidates to fulfil the harsh requirements of hypersonic applications. For more than a decade, ONERA has been actively involved in several programs to develop such materials for different applications (hypersonic flights, propulsion systems ...). In our laboratories, monolithic and composite materials have been investigated as well as several processing methods. In this paper, we present for example the ZrB 2 -SiC and HfB 2 -SiC compositions with TaSi 2 or Y 2 O 3 additions which have been especially studied in the European Projects ATLLAS and ATLLAS 2. Assessments of several prototypes in realistic environment are also described. Furthermore, based on these material developments, a specific study on the oxidation behaviour of such monoliths from 1200°C to 2400°C with a dedicated test bench using a 2 kW CO 2 laser has been carried out (oxidation under air and water vapour atmospheres). Recently, some work on the manufacturing of Ultra-High Temperature Ceramic Matrix Composites (UHTCMC) has been initiated using slurry infiltration and pyrolysis. The behaviour and properties of these materials are encouraging.
