The reaction of metal chlorides with hexamethyldisilazane (HMDS) provides a novel set of syntheses generating metal-hexamethyldisilazide compounds (M-HMDS), which can be used as precursors for functional ceramic materials. The current methods to synthesize M-HMDS are expensive and require multi-step processes; for example, at the moment lithium aluminum hydride is needed to create Al-HMDS, which creates harmful hydrogen gas. Our method of synthesizing Al-HMDS is proving to be a much more efficient method that does not create hydrogen gas: it is easily controlled, low-cost, and scalable. Applications of Al-HMDS include the creation of aluminum nitride (AlN) and silicon carbide (SiC), which are semiconductors that can be used as films or coatings for solid-state batteries. The current methods to synthesize AlN and SiC require high temperatures, are prone to impurities that decrease conductivity, and must undergo multiple processes. It is expected that the novel method can allow for commercial use of AlN and SiC more accessible than it is currently, permitting solid-state batteries to be more viable.
