RF (radiofrequency) ground heating is a method of applying heat to soil at depth and affords a way of thermally desorbing organic contaminants for surface collection and destruction. Soil can be heated to high temperatures, and thus most organic cont

Oxide nonlinear conductors are granular electronic ceramic materials whose electrical behavior is dominated by grain boundary interfaces states. The material is typically comprised of relatively conducting oxide grains with electrical barriers at the

This paper outlines our present understanding of the conduction mechanisms and physical processes relevant to the performance of ZnO−based ceramic varistors. Varistor behavior is determined by the gross ceramic microstructure of the device as well

The complex dielectric constant $\ensuremath{\epsilon}(\ensuremath{\omega})={\ensuremath{\epsilon}}_{1}+i{\ensuremath{\epsilon}}_{2}$ for graphite is derived in the energy range 1 to 0.001 eV by Kramers-Kronig analysis of reflectance data with a suit

High‐frequency, 106≲f≲2×109 Hz, impedance measurements on ZnO‐based ceramic varistors are described. Our studies indicate that the ZnO grain resistivity ρg is less than 1 Ω cm for GE‐MOVR varistors at room temperature. The high‐frequen

Current‐voltage data for metal‐oxide varistors are presented in the temperature range 4.2–420 °K. These results and other general observations concerning varistor behavior are used to help decide which of the several mechanisms employed to exp

Current‐voltage data for metal oxide varistors are presented in the temperature range 100–1300 °C and for current densities as high as 103 A/cm2. The current‐voltage characteristic can be crudely represented at all temperatures by a breakdown

The low‐frequency (100–10−4 Hz) behavior of metal‐oxide varistors is obtained from analysis of the charging and discharging currents which flow upon the application and removal of a step voltage. These results are compared to data for the com

The effect of annealing on the wetting behavior of Bi-rich intergranular phases in ZnO:Bi:Co varistors was studied. The intergranular phase exhibits temperature-dependent grain-boundary wetting, with an average equilibrium dihedral angle of 0° at 11
