The combination of ultrasonic exposure on ceric phosphate gels with subsequent hydrothermal-microwave treatment resulted in the formation of nanoscale NH4Ce2(PO4)3 or KCe2(PO4)3 phases. The sun protection factor (SPF) and protection factor against UV-A radiation (UVAPF) values for double ceric phosphates with the smallest crystallite sizes exceeded 4 and 3.5, respectively, which is much higher than the values for samples consisting of larger particles. These results are superior to previously published values for similar ceric compounds, and thus show promise for their application in sunscreens.

Сочетание ультразвукового воздействия на церийфосфатные гели с их последующей гидротермально-микроволновой обработкой привело к образованию наноразмерных фаз NH4Ce2(PO4)3 или KCe2(PO4)3. Солнцезащитный фактор (SPF) и фактор защиты от УФ-А-излучения (UVAPF) для двойных ортофосфатов церия(IV) с наименьшими размерами частиц превысили значения 4 и 3,5 соответственно, что оказалось значительно выше соответствующих значений для образцов, состоящих из более крупных частиц. Полученные данные превосходят ранее опубликованные значения для аналогичных соединений церия и, таким образом, указывают на перспективность применения полученных соединений в солнцезащитных средствах.
