The response of ZrB2 to simulated plasma-facing material conditions of He irradiation at high temperature

Structural integrity and damage of ZrB2 ceramics after 4 MeV Au ions irradiation

“…It becomes attractive for high-temperature structural applications due to its unique combination of high melting point, high strength and hardness, high thermal conductivity as well as good chemical inertness [13][14][15]. Garrison et al explored the response of ZrB2 to He ions irradiation under 30 keV at temperatures between 920 and 1120 K [7]. They found that the mass losses of the ZrB2 through ion implantation were slightly lower than tungsten, a benchmark material for plasma face in fusion reactor.…”

“…Table 1 lists the melting points of some typical UHTCs, showing their comparable high temperature resistance to tungsten. However, resistance to irradiation by particles and neutrons has drawn researchers' attention only recently [7][8][9]. In this paper, we are presenting our most recent study of zirconium diboride, one of the UHTC compounds, and showing its inherent capability in resisting irradiation damage, followed by deep understanding of what happened at lattice level when it is irradiated by heavy ions.…”

Anti-ablation properties of ZrB2 modified carbon/phenolic composites in plasma wind tunnel

“…ZrB 2 is a kind of ultra-high temperature ceramic, its melting point is very high in the absence of oxygen, and the volatilization of boron oxide (B 2 O 3 ) produced at high temperatures may enhance the thermal blocking effect. 23,24 Amirsardari et al 25 studied the thermal stability of GO/C/Phenolic Nanocomposite by introducing zirconium boride (ZrB 2 ) under oxyacetylene tests. They found that the ZrO 2 layer plays an essential role in improving anti-ablation properties, but did not conduct detailed research on the effect of ZrB 2 content.…”

Self-contained dual-scale composite architectures in spray dried zirconium diboride

“…In addition to the thermophysical and thermochemical robustness of zirconium diboride, the absorption of thermal neutrons, by boron-10, which leads to the release of helium-4 ( 4 He) and lithium-7 ( 7 Li) products [15] is used to control the reactivity in fission fuels, hence the application of zirconium diboride coatings as integral fuel burnable absorbers in pressurised water reactors [16], [17]. Data on zirconium diboride's response to fusion irradiations is growing, for example He+ at 30 keV with fluences of up to 5.0×10 22 have been studied for tokamak applications [18]. Spray drying, a particle engineering process, has found wide and established applications in pharmaceutical, food and ceramic industries.…”
