Preparation of strontium peroxide
Strontium peroxide is obtained from strontium hydroxide and hydrogen peroxide.
Five grams of anhydrous strontium nitrate (or the equivalent weight of the 4-hydrate) are dissolved in 50 ml of 3% hydrogen peroxide and mixed with a solution of 7 ml of concentrated aqueous ammonia in 100 ml of water. As described under the procedure for barium peroxide the SrO2 8-hydrate is converted to the anhydrous compound by heating it at 800°C for about 4 hours in dry carbon dioxide free oxygen. The yield of SrO2 is 2.5-3 g.
