A kind of biological cemmics that is nearly inert and is composed of high-purity alumina, also known as pure corundum biological cemmics. polycrystal has high strength, High hardness, small friction coefficient, low wear rate, and its friction coefficient and wear rate also decrease with the increase of water vapor pressure. It is especially suitable for manufacturing prosthesis with high requirements for wear resistance such as artificial joint heads and mortars. alumina bioceramics are not corrosion or dissolved in physiological environment. The combination between dense ceramics and tissues is morphological, while the combination between porous ceramics and tissues is biological. It can also be used as dental implant, ear and hearing bone prosthesis, bone screw and drug delivery carrier.
