Study on preparation and properties of zinc ferrite and titanium dioxide

In this paper, sulfuric acid leaching high iron zinc calcine was used to prepare and purify ferrite, temperature roasting method synthetic sol-gel TiO 2 . The properties of the prepared samples ware characterized by XRD, FT-IR, BET, SEM other methods. results show that ferrite is pure purified contains impurities PbSO 4 crystal form prepares at calcination 300~550°C basically same, transformation occurs 550~600°C. calcines 400°C (T400) have higher specific surface area, larger total pore volume average diameter. crystalline degree high, micropores on are closed, grains bond with each other. diameter than those ferrite. effects structure adsorption capacity catalytic efficiency as follows: T400> > synthesized
