In ultima analisi, a strati alterni, i monostrati si troveranno nella stessa posizione ed ogni anione PO₄<sup>3-</sup> sarà a contatto con altri 6 anioni. </p><p>Da questa struttura cristallina deriva la formazione di tunnel d'importanza non trascurabile. Essi infatti vengono di solito occupati da ioni calcio, ossidrilici e floruro. Inoltre proprio la natura ionica del cristallo permette la sostituzione di ioni del reticolo con altri di analoga grandezza e carica come tutti gli alogeni, AsO<sub>4</sub><sup>3-</sup>, HPO<sub>4</sub><sup>2-</sup>, Sr<sup>2+</sup>, Ba<sup>2+</sup>, Pb<sup>2+</sup>. </p> <div class="mw-heading mw-heading3"><h3 id="Parametri_cristallografici">Parametri cristallografici</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Apatite&veaction=edit&section=4" title="Modifica la sezione Parametri cristallografici" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Apatite&action=edit&section=4" title="Edit section's source code: Parametri cristallografici"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size mw-halign-center" typeof="mw:File/Thumb"><a href="/wiki/File:Fluorapatite-unit-cell-3D-balls.png" class="mw-file-description"><img alt="Unité cellulaire de l'apatite" src="//upload.wikimedia.org/wikipedia/commons/thumb/7/7f/Fluorapatite-unit-cell-3D-balls.png/220px-Fluorapatite-unit-cell-3D-balls.png" decoding="async" width="220" height="196" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/7f/Fluorapatite-unit-cell-3D-balls.png/330px-Fluorapatite-unit-cell-3D-balls.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/7f/Fluorapatite-unit-cell-3D-balls.png/440px-Fluorapatite-unit-cell-3D-balls.png 2x" data-file-width="1100" data-file-height="978" /></a><figcaption> Cella unitaria dell'apatite. </figcaption></figure> <ul><li>Parametri della cella unitaria: a = 9,367, c = 6,884, Z = 2;
