Three-dimensional silicates are formed by sharing all four oxygen atom of ${{\mathrm{SiO}}_4}^{4-}$. Ultramarines, feldspars and zeolites are examples of three- dimensional silicates. Molecular formula of ultramarine is ${\mathrm{Na}}_8{\left({\mathrm{SiAlO}}_4\right)}_6$ feldspar is ${\mathrm{KAlSi}}_3{\mathrm{O}}_8$ and zeolite is ${\mathrm{Na}}_2{\mathrm{Al}}_2{\mathrm{Si}}_2{\mathrm{O}}_8. {\mathrm{xH}}_2\mathrm{O}$.
