Abstract: The effect of substituting chlorate ions for nitrate ions on the transport properties of K (NO3) 1-x (ClO3) x has been investigated. The electrical resistivity, dielectric constant, loss tangent and thermal conductivity of K (NO3) 1-x (ClO3) x have been studied. The electrical resistivity-temperature curve for the x = 0.1 sample shows an anomaly on heating and on cooling which indicates a first-order phase transition. Anomalies in the dielectric constant-temperature curves, also on heating and on cooling, confirm the first-order phase transition. The introduction of chlorate ions lead to scattering which increases the phononphonon interaction. This results in the decrease in thermal conductivity.
