| Abstract: | A simple method for measuring the dielectric parameter of materials in the form of powders at microwave frequencies is suggested.
Measurement of the permittivity ε′ and ge″ at 9·967 GHz on powder samples of the aluminum ore bauxite gives interesting results.
It is found that ε′ and ε″ increases with packing densities (δ ). Further ε′ and ε″ also depend upon the percentage of Al2O3. These results show that the values of ε′ and ε″ can be used to set certain basic values for minability of the ore for a
particular sample. Conductivities (σ) and relaxation (τ) are also calculated in the present studies |
