Abstract
A novel process is described for preparing dense, polycrystalline tricalcium phosphates. Singleβ-phase compositional integrity is achieved by introducing catalytic amounts of sulphate ion and this pore free material has close to theoretical density. Preliminary mechanical properties include a compression strength of 687 MN m−2 and a tensile strength of 154 MN m−2. The relationship between processing variables and phase composition, microstructure, strength and translucence is described. The material has promise for bone implant applications.
