Alumina ceramic is the most mature engineering ceramic, offering excellent electrical insulation properties combined with high hardness and superior wear resistance. While it has relatively lower strength and fracture toughness, its thermal stability makes it ideal for high-temperature applications. The material typically appears white but may also be pink or ivory depending on sintering additives or raw material impurities.
