· JVASP-103521· Al2CO

Al₂CO is an experimental ceramic compound combining aluminum, carbon, and oxygen in a mixed-valence or carbide-oxide structure. This material belongs to the family of advanced ceramics and represents ongoing research into hybrid ceramic systems that may offer combinations of hardness, thermal stability, and mechanical strength not easily achieved in conventional single-phase ceramics. While not yet widely commercialized, Al₂CO and related aluminum carbide-oxide phases are of interest for high-temperature structural applications and wear-resistant coatings where the interplay between covalent carbide bonding and oxide stability could be exploited.
