== Chemistry and related species == Stilbite shows a wide variation in exchangeable [[cations]]: [[silicon]] and [[aluminium]] ions occupy equivalent sites and can substitute for each other. Since silicon and aluminium have a different charge (Si<sup>4+</sup> and Al<sup>3+</sup>) the ions occupying the sodium/calcium site have to adjust to maintain charge balance. There is a continuous [[Solid solution|series]] between [[stellerite]], whose formula can be written as Ca<sub>4</sub>(Si<sub>28</sub>Al<sub>8</sub>)O<sub>72</sub>Β·28(H<sub>2</sub>O), and stilbite, and another continuous series between stilbite and [[barrerite]], Na<sub>8</sub>(Si<sub>28</sub>Al<sub>8</sub>)O<sub>72</sub>Β·26(H<sub>2</sub>O). [[Epistilbite]] is a distinct zeolite species unrelated to stilbite.
