Study the Effect of Calcium Peroxide on Qualitative Number of Technological Parameters
Proposals a technology for producing calcium peroxide from a 30% calcium nitrate solution with pH = 4-5 and aqueous solutions of ammonia and 40% hydrogen peroxide cooled to 10 ° C. It was found that, in contrast to the known methods, increase of molar ratio will does not lead to a significant increase yield of calcium peroxide. Consequently, choosing a particular synthesis methodology is always tedious in light of the lack of a single detailed literature covering the comparison and effects of different synthesis procedures. Crystalline preparations with more than 90% CaO2·8H2O can be obtained only from dilute solutions of calcium nitrate, ammonia and hydrogen peroxide. The use of concentrated solutions promotes the formation of amorphous formations with an indistinctly expressed structure. The study’s results made it possible to establish the storage conditions of calcium peroxide depending on the time, which is very important when selling the product to consumers.
