 (sĭ-lŏk′sān′, sī-)
Any of a class of chemical compounds of silicon, oxygen, and hydrogen, based on the repeating structural unit H2SiO.


(Elements & Compounds) any of a class of compounds containing alternate silicon and oxygen atoms with the silicon atoms bound to hydrogen atoms or organic groups. Many are highly complex polymers. See also silicone
