The structures and chemical states of SiO2/α-FeOOH and SiO2/α-Fe2O3 fine particles have been investigated by the technologies of HREM, XPS and CELS. The results show that a crystalline interface layer between SiO2 coating and α-FeOOH nucleus is formed, and its chemical composition is infered to be α-Fe2O3. In view of this, a mechanism of its formation is presented. The results also show that the coating of SiO2/α-Fe2O3 obtained from SiO2/α-FeOOH by a thermal treatment is converted from an amorphous to crystal, line one and its mechanism is discussed. In addition, the effects of the coating on the structure of vacant state above Fermi level of α-FeOOH fine particles have also been studied.
