В стандартных условиях проведен модельный эксперимент по влиянию сил обеднения на процесс высыхания капли взвесей невзаимодействующих частиц аэросил – полистирольный латекс. Впервые обнаружен быстропротекающий процесс фазового превращения аэросила в кристаллический SiO2 в течение десятков секунд, сопровождающийся резким изменением цвета раствора от светло-голубого до синего. Обнаружена дифракционная картина, свидетельствующая о нанокристаллической природе зародышеобразования новой фазы. Фазообразование интерпретировано как результат действия неравновесной силы обеднения в условиях гидродинамической неустойчивости высыхающей капли.
