Silicon-Phosphorus-Antimony Ion Exchangers and Their Use in Glass Hardening Baths

Resumo

It is found that the samples of silicon-phosphorus-antimony ion exchangers obtained in experimental batches are close in terms of their properties to the sample obtained under laboratory conditions, and they exhibit identical characteristics in regeneration of potassium nitrate melt. In order to optimize the process of ion exchange strengthening of glass it is proposed that two ion exchangers be introduced into the melt: K[Sb(OH)₄] for sorption of Na⁺ ions and silicon-phosphorus-antimony for polyvalent impurity ions.
