Gains will be driven by the development of new applications for advanced ceramics and by their increased adoption in already established applications based on superior performance and material properties. Advanced structural ceramics are being used or have the potential to be used in a large variety of applications ferber and tennery 1991 american ceramic society website some of the primary application areas are listed in table 1 this is not intended as a complete list but rather a sampling of some of the applications with the greatest potential and or the greatest interest.
