Thiosilicate

In chemistry and materials science, thiosilicate refers to materials containing anions of the formula SiS(2+n)]2n-. Derivatives where some sulfide is replaced by oxide are also called thiosilicates, examples being materials derived from the oxohexathiodisilicate [Si2OS6]6-. Silicon is tetrahedral in all thiosilicates. Formally such materials are derived from silicon disulfide in analogy to the relationship between silicon dioxide and silicates. Thiosilicates are solids that are typically colorless. They are characteristically sensitive to hydrolysis.

Materials science

The LISICON (LIthium Super Ionic CONductor) include thiosilicates, which are fast ion conductors.[1] Thiosilicates and related thiogermanates are also of interest for infra red optics, since they only absorb low frequency IR modes.[2]

gollark: Venusing Earth is probably quite hard. Although I think it'll happen naturally in a billion years or so.
gollark: This would be bad for technology, slow and/or wildly unethical, and not very helpful except under negative utilitarianism.
gollark: Subsistence farming is actually boring and unpleasant though. It is good that we stopped doing it. Although "monke" would be hunter-gathering, strictly. Which is no longer possible at scale due to loss of habitats and population growth.
gollark: That would be silly. I just do things at the correct time.
gollark: Because of rampant nonconsecutive version numbers in phones, 2060 through 2078 actually happen after 2093.
