ABSTRACT:
The present invention provides lubricant compositions for the powder metallurgical field. The lubricant compositions contain a solid phase lubricant such as graphite, molybdenum disulfide, and polytetrafluoroethylene in combination with a liquid phase lubricant that is a binder for the solid phase lubricant. The binder can be chosen from various classes of compounds including polyethylene glycols, polyethylene glycol esters, partial esters of C.sub.3-6 polyhydric alcohols, polyvinyl esters, and polyvinyl pyrrolidones. The binder is solubilized in an organic solvent.
