With the high melting point, good thermal and electrical conductivities, a less explored layered MAB phase WAlB may prove beneficial for futuristic applications. In this present paper, a successful synthesis method of highly pure WAlB phase under an open atmosphere following the molten salt route is reported. In this method, a two-step heating profile was used to produce sub-micron sized particles. Template growth of layer WAlB from layered W–Al intermetallics is revealed after careful examination using XRD, SEM, and thermal analysis. The WAlB phase was found thermally stable until 800 °C under an inert atmosphere and until 500 °C under an open atmosphere after investigating the respective XRD, thermal analysis, and SEM data.

揭示在开放气氛下合成的层状亚微米 MAB 相 WAlB 的形成机制、热稳定性和氧化稳定性

由于具有高熔点、良好的导热性和导电性，较少探索的层状 MAB 相 WAlB 可能对未来的应用有益。在本文中，报道了一种在开放气氛下遵循熔盐路线成功合成高纯WAlB相的方法。在该方法中，使用两步加热曲线来生产亚微米尺寸的颗粒。使用 XRD、SEM 和热分析仔细检查后，揭示了层状 W-Al 金属间化合物中 WAlB 层的模板生长。在研究了各自的 XRD、热分析和 SEM 数据后，发现 WAlB 相在惰性气氛下热稳定至 800 °C，在开放气氛下热稳定至 500 °C。
