摘要:
Nanoparticles are claimed which consist of 50-99.99% by weight of alumina and 0.01-50% by weight of metal oxide of elements of main group I and II of the Periodic Table. These nanoparticles are obtained by drying a suspension of aluminum chlorohydrate, oxide formers and, if desired, crystallization nuclei, followed by calcining and comminution of the resultant agglomerates.
