ON ANIONIC SPECIES OF SiO_2-CONTAINING SODIUM ALUMINATE SOLUTIONS
|
Abstract:
The anionic species of the SiO_2-containing sodium aluminate solutions preparedby different methods have been investigated by Raman spectra and ultraviolet spectra. It wasfound that these solutions contain different Si-containing anions. The solution prepared byleaching industrial sinter of soda-lime sintering process contains polysilicate ions with Si-O-Siradicals.
