Влияние Отжига В Разных Средах На Свойства Нанопорошка Фторида Кальция

Abstract

Using a pulsed electron beam evaporation in vacuum a mesoporous nanopowder CaF2 with a specific surface area up to 60.5 m2/g were produced. The effect of annealing in different media on the evolution of magnetic and texture properties of CaF2 nanoparticles has been studied. For the first time, the effect of annealing medium on the specific surface area and magnetization of CaF2 nanopowders was discovered.
