The study was carried out on the lithium Lubricants in the molten state under the effect of tempearture, shear stress (τ), and shear rate (γ) by using capillary viscometer, the corrections have been done to expermintal data. It was found from the obtained results that, real viscosity ηc decreased with increasing real shear rate (γc). Also it was found that the lithium Lubricants is a pseudoplastic material (n<1).
