..., suggested that Mg 2+ ions are substituted into the Ca 2+ positions. The apatites became less well crystallized and more unstable with the increase of magnesium content. The amorphous sample synthesized at the magnesium-calcium feed molar ratio of 1 revealed a tricalcium phosphate pattern after ignition...

...J.C. Voegel; R.M. Frank A single crystal electron diffraction study has been carried out on normal and carious human apatites from contiguous enamel areas of the same human tooth. Whole rows of the reciprocal space have been measured and after determination of plane equidistances...

...Racquel Z. LeGeros; Ming S. Tung Apatites containing CO 3 and/or F were synthesized and exposed to acid buffer. The extent of dissolution was determined (as m M Ca/ml buffer solution) and the apatites characterized by X-ray diffraction, IR absorption, and chemical analyses before and after acid...
