Embodiment 1
[0019] Accurately weigh 0.5g of commercially available analytical pure magnesium oxide, add 15ml of deionized water to a 250ml beaker, dissolve and grind for about 1 hour to obtain a magnesium oxide slurry with a mass percentage of about 3.2%. Weigh 1g of commercially available analytically pure ammonium chloride and dissolve it in 15ml of commercially available hydrogen peroxide with an analytically pure mass fraction of about 30%. After mixing completely, slowly add it to the ground magnesium oxide slurry while stirring. The reaction was continued for 3.5 h under mechanical stirring to obtain a white mixture, which was vacuum-dried at -80°C after suction filtration. The target product nano magnesium peroxide powder is obtained.
[0020] Tested by X-ray diffractometer figure 1 The XRD spectrum of the nano-magnesium peroxide prepared in Example 1 of the present invention is compared with the standard card, showing that the prepared substance is magnesium peroxide with a purit...
Embodiment 2
[0023] Accurately weigh 1 g of commercially available analytical pure magnesium oxide, add 25 ml of deionized water to a 250 ml beaker, dissolve and grind for 1.5 hours to obtain a magnesium oxide slurry with a mass percentage of about 3.8%. Accurately weigh 2g of commercially available analytically pure ammonium chloride and dissolve in 35ml of commercially available hydrogen peroxide with an analytically pure mass fraction of about 30%, and continue to react for 4h under mechanical stirring at 500r / min to obtain a white mixed solution. Freeze and vacuum dry at -80°C. The target product nano magnesium peroxide powder is obtained.
[0024] Tested by X-ray diffractometer figure 2 The XRD spectrum of the nano-magnesium peroxide prepared in Example 2 of the present invention is compared with the standard card, showing that the prepared substance is magnesium peroxide with a purity of 52%. Contains small amounts of magnesium oxide and magnesium hydroxide.
