Summary

  1. 1.

    A study of the dehydration process and the data from thermal investigations with a recording pyrometer have permitted the establishment of the individuality of each of the compounds SrO2, SrO2· 8H2, SrO2· H2O2, and SrO2 · 2H2O2.

  2. 2.

    Active oxygen is removed from the perhydrates with an exothermic effect at ≈75°, and from strontium peroxide at ≈450° with an endothermic effect. Water is removed stepwise in the dehydration at +80° and 100° for SrO2 · 8H2O.

  3. 3.

    The hydrates and perhydrates investigated go over to SrO2 upon dehydration.

  4. 4.

    The peroxide compounds of strontium investigated, except for the diperhydrate are stable at room temperature. The diperhydrate of SrO2 (SrO2 · 2H2O2) decomposes at-5°.

  5. 5.

    Data from x-ray and crystallooptical investigations confirm the individual nature of the peroxide compounds of strontium found in the study of the system Sr(OH)2-H2O2- H2O.
