Calcium cyanamide (CaCN₂) is an inorganic ceramic compound primarily known as a nitrogen-fixing fertilizer and chemical intermediate rather than a structural ceramic. It is produced industrially through the carbothermic reduction of calcium carbonate in the presence of nitrogen, and serves dual roles as an agricultural nitrogen source and a precursor for synthesizing other nitrogen-containing compounds such as melamine and urea. While not typically selected for load-bearing or high-temperature structural applications, CaCN₂ is valued in agrochemical and fine chemical synthesis contexts for its reactivity and nitrogen content, and emerging research explores its potential in ceramic composites and as a raw material for advanced nitrogen ceramics.
