Alumina is the most well-known and most commonly used fine ceramic material. It has the same sintered crystal body as sapphire and ruby. It has been used for decades in electrical components for its high electrical insulation, and is widely used in mechanical parts for its high strength, and corrosion- and wear-resistance.
