The effect of magnetized water on TiO₂ based varistors

The effect of magnetized water on TiO₂ based varistors was investigated. The results of the electrical behavior reveal that the water magnetized at 0.2 T yielded lower varistor voltage and the water magnetized at 0.3 T yielded higher varistor voltage compared to non-magnetized deionized water. The XRD and EDAX results show that the main polycrystalline phase is rutile TiO₂ surrounded by the second phase composed of Ce, Si, and Ti. The SEM micrographs suggest more preferable microstructure may be obtained by using the 0.2 T magnetized water. The role of the magnetized water was examined by the perturbation of the gas-to-liquid interface that changes inter-particle forces, and consequently leads to higher electrostatic stabilization of the slurries.
