Effect of added trace elements on the dielectric properties of bone

ABSTRACT

The dielectric properties [dielectric constant and dielectric loss] of hydrated solid and powdered bone are determined at 10 kHz and at the temperature range 25C-230C. The effect of mixing dehydrated powdered bone with certain added trace elements [Li2CO3, Na2CO3, MgO, Al2O3, PbO and ZnO] in 10% proportions by weight on the dielectric properties was also studied. Measurements were carried out, on disc shaped samples using standard bridge techniques. Results on dielectric constant and its variation with temperature show that addition of Li2CO3, ZnO and PbO had desired effects. The results also showed how the dielectric properties are related to the structure of bone material:
