· JVASP-9685· ScAl3C3

ScAl3C3 is a ternary carbide compound combining scandium, aluminum, and carbon, belonging to the family of transition metal aluminides and carbides. This material is primarily of research and developmental interest rather than widely established in production, with potential applications in high-performance structural and thermal applications where lightweight combined with ceramic-like hardness is advantageous. The compound's appeal lies in its ability to bridge properties between metallic and ceramic phases, making it a candidate for advanced aerospace and high-temperature engineering where weight reduction and wear resistance are critical design drivers.
