Summary

1. A study of the reaction of sodium and potassium metaniobates with hydrogen peroxide at 0° showed that for low H2O2 concentrations (3–6%) peroxide compounds of niobium are formed Na(K)NbO4· nH2O (n=1.5–3.5). With high H2O2 concentrations (10–54%) the compounds formed are not those described in the literature but more soluble peroxide compounds of the perhydrate type Na(K)NbO4-nH2O2· mH2O (n=1.3–1.5; m =1.5-3), rather unstable at 0°.

At −10° the perhydrates of permetaniobates form in a more stable form and with a higher content of active oxygen (11–12.3%); they were separated and studied in the solid state.
