Soft Ferrite Pressure Sensors: Study 1 (Fein, Castle, Fisher & Campbell): Varying PVA as a Binder for Potential Soft Ferrite Pressure Sensors

Institution

Northern Kentucky University

Abstract

Binder application experiments of ferrite powders were carried out in order to determine sufficient binder content of toroidal bodies. Large-scale application of binder solution to these powders, such as in powder metallurgy industry, require expensive machinery; their costs however are not conducive to undergraduate research laboratories. A low cost binding process was therefore developed using various amounts of polyvinyl alcohol (PVA) to achieve optimal porosity of the powders after pressing. Scanning-Electron Microscopy and Elemental X-Ray Diffraction were then carried out and the effect of binder content on the porosity of pressed bodies was examined.
