Abstract


Zinc substituted β-tricalcium phosphate [β-Ca3(PO 4)2] was formed by substituting a zinc precursor in calcium-deficient apatite through aqueous precipitation technique. Heat treatment at 1000°C led to the formation of well crystalline β-Ca 3(PO4). Refinement technique was used to determine the influence of incorporated zinc in the β-Ca3(PO4) structure. The structural data for all the four different zinc substituted β-Ca3(PO4) ranging from 0-9 mol% of zinc investigated in the present study confirmed the rhombohedral structure of β-Ca 3(PO4) in the hexagonal setting (space group R3c). The incorporation of lower sized Zn2+ (0.745 Å for sixfold coordination with O) at the higher sized Ca2+ (1.00 Å for sixfold coordination with O) site in the β-Ca3(PO4) structure led to the contraction of unit cell parameters. The added zinc prefers to occupy the Ca(5) site of β-Ca3(PO4) structure. © 2009 The American Ceramic Society.
