Effect of Calcium Carbonate on Microwave Dielectric Behavior of Soils

چکیده
An attempt has been made to study the impact of calcium carbonate on soil dielectric properties. The dielectric constant (ε') and dielectric loss (ε'') of soil with increasing percentage of calcium carbonate are measured at 7.0 GHz. These measurements are carried at room temperature. The J-band microwave setup with slotted section and a crystal detector is used for measurements. The two point method is found suitable for these measurements. Abrupt change in values of dielectric constant and dielectric loss due to addition of calcium carbonate is observed. This data is used to determine the a.c. electrical conductivity, relaxation time, and tangent loss. The dielectric properties of soils are in good agreement with the earlier reported work.

An efficient solid-state approach was established to synthesize (K0.5Na0.5) NbO3 ceramics using calcination kinetics and microwave assisted sintering. Milling of carbonate and oxide raw materials were carried out for 15h to obtain homogeneous nano particles. The crystallite size of 5.30 nm was obtained for the KNN system after calcination through optimized parameters and observed to be stoichio...

ABSTRACT-This experiment was carried out to study particle size distribution (PSD) of carbonates in soils and its effect on some calcareous soil properties in Khuzestan Province, Iran. Soil samples (n=72) were collected from different regions. To evaluate the effect of carbonates on water contents at pressure head of -1500kpa and PSD of soil samples, these properties were determined before and ...
