ceramic

· KH2N

KH2N is a layered ceramic compound belonging to the nitride family, characterized by a two-dimensional crystal structure with weak interlayer bonding. This material is primarily of research interest for applications requiring lightweight ceramics with tunable mechanical properties, particularly in advanced composites and functional coatings where layer-by-layer exfoliation and reassembly offers design flexibility.
