ABSTRACT:
The invention provides CaCO3/SiO2.nH2O nanocomposite particles and method of producing the same. A template nucleus is used calcium carbonate and the surface of nucleus is encapsulated by a SiO2.nH2O nanolayer. The invention also provides a CaCO3/SiO2.nH2O nanocomposite particles having hollow structure, in which n=0-2. The nanocomposite particles according to the invention have a number of uses.
