RuO2,　IrO2　and　PdO　are　the　most　frequently　employed　active　oxides　in　titanium　anode　coatings,　so　studies　on　the　kinetics　of　their　crystal-growth　are　important　for　anode　material　preparations.　In　this　paper,　the　particle　growths　of　RuO2,　IrO2　and　PdO　with　increased　temperature　were　discussed.　The　least-squares　method　was　used　to　fit　the　kinetic　data.　As　a　result,　the　two-stage　phenomena　are　found　in　all　three　noble　material　systems.　The　linear　regression　equations　are　correct　both　for　the　first　and　second　stages.　It　is　suggested　that　based　on　the　corresponding　kinetics　equation　Ln　D　=　-QL/kT　+　a,　the　sizes　of　oxide　particles　can　be　controlled　for　the　three　noble　oxides.
