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.　(C)　2003　Elsevier　Ltd.　All　rights　reserved.
