Development of Superplastic Functional Ceramics Through Grain Refinement
Chapter
Abstract
Functional ceramics include those ceramics that have characteristic properties such as electronic, magnetic, optical, chemical, or biological properties. Superplasticity of the bioceramic, hydroxyapatite, may be the first example of superplastic elongation in a functional ceramic. Superplasticity in ZrO2 can also be utilized as a unique forming method for the solid electrolyte for fuel cells. In this paper, the superplasticity of piezoelectric PbTiO3 (lead titanate) is studied.
