The disclosed technology relates to a dispersion comprising LiOH and/or LiOH.H2O particulates dispersed in an organic medium comprising at least one oil and at least one surfactant, the concentration of LiOH and/or LiOH.H2O particulates in the dispersion being greater than 10% by weight, the LiOH and/or LiOH.H2O particulates having a mean particle size in the range up to about 10 microns wherein at least about 99% by weight of the LiOH particulates have a particle size in the range up to about 20 microns. A process for making the dispersion is disclosed. Grease compositions made using the dispersion are disclosed.
L'invention concerne une dispersion comprenant des particules de LiOH et/ou LiOH.H2O dispersées dans un milieu organique comprenant au moins une huile et au moins un agent tensioactif, la concentration de particules LiOH et/ou LiOH.H2O dans la dispersion étant supérieure à 10 % en poids, les particules de LiOH et/ou LiOH.H2O ayant une taille de particule moyenne dans la plage jusqu'à environ 10 microns, au moins 99 % en poids des particules de LiOH ayant une taille de particule dans la plage jusqu'à environ 20 microns. L'invention concerne également un processus de fabrication de la dispersion. Des compositions de graisse réalisées en utilisant la dispersion sont également décrites.
