- n. any salt or ester of orthosilicic acid, (M+)4SiO44− or Si(OR)4
- n. any silicate mineral, such as garnet or olivine, in which the SiO4 tetrahedra do not share oxygen atoms with each other

- n. A salt of orthosilicic acid (H4SiO4). Zinc orthosilicate (Zn2SiO4 or 2ZnO. SiO2) is the mineral willemite: it is often called a unisilicate, since it has an oxygen ratio of 1:1.

It also had a million ton thermal storage unit using iron orthosilicate (copper slag).
Two important considerations are the carbon-oxygen and magnesium-silicon ratios of stars, which can affect whether a planet has certain magnesium- or silicon-loaded clay minerals such as magnesium silicate (MgSiO3), silicon dioxide (SiO2), magnesium orthosilicate (Mg2SiO4), and magnesium oxide (MgO).
Lauritzen and his peers used an yttrium orthosilicate crystal doped with erbium ions to store light pulses on the single-photon level.
The new technique raises the efficiency to 69 per cent, using a solid-state device which stores data on ions in a crystal made of an exotic compound, yttrium orthosilicate.
