Some trace elements have potential to expand the lattice parameters of the synthetic apatite crystal cell along the a-axis such as ferrous (Fe2+), ferric (Fe3+), strontium (Sr2+) and zinc ions (Zn2+) (molar fraction >10%) whereas it shrinks with silicate (SiO44-), carbonate (CO32-), magnesium (Mg2+), Zn2+ (molar fraction < 10%) and titanium ions (Ti4+).SiO44-, CO32-, Zn2+, Fe2+, Fe3+ and strontium ions (Sr2+) can increase the lattice parameters along the c-axis, decreased by Mg2+, nickelous (Ni2+), chromic (Cr3+), cobaltous (Co2+) and Ti4+.
