Ceramic materials used in total joints belong to a class of materials called oxide ceramics. These materials are formed by close packed crystals of oxides of aluminum or zirconium metals. The arrangements of the crystals and the presence of impurities determine the characteristics of the resulting material. Hopefully you now also understand that the ceramic materials used in total hip prostheses have nothing to do with the pottery used on your dining table. The commercial ceramic products are not only brittle; the body does not tolerate them! Excelsior Ceramics offers a broad range of ceramic materials to meet your exact needs for a wide variety of applications. With decades of experience, we can supply these materials as finished components, unfinished, machined blanks, pressed near net shape blanks, high volume pressed net shape components, and complex, highly machined parts.
