Abstract
The goal of this research was to investigate ways to increase the structural integrity of ferrite compounds for magneto-elastic pressure applications. We successfully synthesized ferrite composite materials of MnxFe3-xO4 using thermal decomposition of metal oxides. These ferrite materials have been observed to change their inductance due to external pressure. This property can be exploited for potential pressure sensor application. We have tested various sample preparation methods to increase structural integrity of these materials. The SEM results show that the frequent grinding of the sample powder reduced the porosity. Additionally double calcination also reduced the porosity, thus allowing the crystals to compact better. We will compare our results to previously obtained results and discuss the improvements.
