<div>I thought apatite corresponds to several calcium phosphates,
not to the one covered by entry 7202572.</div>

<p>I also though that 'apatite' refers to phosphates, not silicates.</p>
<p>The paper, however, claims in the title: "Oxide ion conduction in
Ba, Ca and Sr doped apatite-type lanthanum silicates", i.e. these
are silicates that apparently have an apatite-like structure
(although I am also not an expert in the field). Also, in the
source CIFs that are provided as supplementary materials and which
were the source of the COD data, another structure from this paper
is called "_chemical_name_common 'Ba doped apatite'".</p>
<p>Apparently the authors think that it is appropriate to call their
investigated materials 'apatite'.</p>
<p>In this case, COD leaves the authors' opinion in the entry. Also,
we do not regularise '_chemical_name_common' and will probably
never do that, since this is, eh, a common name which can be
different in different communities.</p>
<p>In the searches it is better to rely on formula (especially the
calculated one), systematic names (these might be regularised in
the future) and crystallographic parameters.</p>
<p>I hope that clarifies the situation and serves you data search
needs...</p>
<p>Regards,<br>
Saulius<br>
