Webβ-tricalcium phosphate (β-TCP) is one of the most common bioceramics, widely applied in bone cements and implants. Herein we synthesized β-TCP by solid state reaction in the presence of increasing am WebThe spectrum for apatite (Fig. 1) conforms to the vibrational require-ments of C3v symmetry for the phosphate ion (Table 1) and suggests that the POr3- group in apatite has or approaches this symmetry; hence, the molecule apparently has higher symmetry than the surrounding crystal field. This interpretation is supported by the data of Fischer ...
