· JVASP-96964· AlH3O3

AlH₃O₃ is an aluminum hydroxide-based ceramic compound that exists primarily in research and experimental contexts rather than widespread industrial production. This material belongs to the family of layered hydroxide ceramics, which are being investigated for applications requiring combinations of low density, moderate stiffness, and potential exfoliation characteristics. The compound's notable layered structure and low exfoliation energy make it of particular interest for researchers exploring laminated composites, structural ceramics, and potentially 2D material derivatives, though industrial-scale applications remain limited.
