PROBLEM TO BE SOLVED: To provide a stable colloidal suspension, which exhibits good frictional properties, oxidation inhibition and anti-wear performance and also lower discoloring, when it is used as a lubricating oil additive for lubricating an oil composition. SOLUTION: The stable colloidal suspension comprises: (a) a dispersed phase comprising a major amount of dispersed hydrated polymeric compounds selected from the group consisting of polymolybdates, polytungstates, polyvanadates, polyniobates, polytantalates, polyuranates, and mixtures thereof, and, (b) an oil phase comprising a dispersing agent and a diluent oil. Processes for preparing the stable colloidal suspensions and their use in lubricating oil compositions are also provided. COPYRIGHT: (C)2005,JPO&NCIPI |
