Preparation and Characterization of MgFe₂O₄/TiO₂ Nano particles by Combined Process for Sensor Applications

The trinary or tetranary metal oxides has lot of prominence in the application of fields in science and technology. Most of the transition metal oxides have the compatibility with neighbor metal or transition metal oxides. Recent trends fallows the developments of nano size materials of metal and metal oxide particles are highly pursued because of their importance in different fields of science and technology applications. In all the transition metal oxides, MgFe₂O₄ is mixed with TiO₂ is a potential candidate for the many applications. MgFe₂O₄ was made by solution combustion process, TiO₂ was added to the sample to (MgFe₂O₄)_1-x/(TiO₂)_x i.e., (0<X<1.0) by wet grinding for 2 hr, then mixed powder was annealing to a temperature of 500oc. Further these materials were used for sensor application. The MgFe₂O₄ is mixed with TiO₂ nano particles were characterized by studying their structure with X-ray diffraction, optical studies were carried out with UV-Vis spectrophotometer and the thermal analysis with TG/DTA.
