Abstract
An object is to provide a cage silicate that can be industrially safely and simply produced by using an alkali silicate solution that does not generate alcohol as a Si raw material and using non-toxic quaternary ammonium, and a method for producing the same. The problem is solved by the following cage silicate:A cage silicate consisting of anion component 1 represented by following formula (1), anion component 2 which is a mineral acid ion, cation component 1 represented by following formula (2), and cation component 2 which is an alkali ion, in which, to the mole number in terms of SiO2, a ratio of the mole number of water, (H2O/SiO2), is 0.7 to 30, a ratio of the mole number of alkali ions, (alkali ions/SiO2), is 1.0×10−7 to 1.0−10−2, and a ratio of the mole number of the mineral acid ions, (mineral acid ions/SiO2), is 1.0×10−7 to 1.0×10−3.In formula (2), R represents an alkyl group having 2 to 20 carbon atoms.
