Description

General description

β-tri-Calcium phosphate belongs to the category of calcium-phosphate based ceramics, which has been involved in the preparation of a new biosynthetic material possessing morphogenetic activity that is used as a bone implant.

Analysis Note

Phase Composition (by XRD analysis)
Low crystalinity Hydroxylapatite at unsintered condition.
A high crystalinity β-Tricalcium phosphate after sintering at 1100C.
β-TCP: >98% (by x-ray diffraction analysis)
other Ca-P phases as Hydroxylapatite, a-TCP and Pyrophosphate <2.0%
