Abstract

The present invention relates to improved metallurgical powder compositions that incorporate solid lubricants, methods for preparing and using the same, and methods of making compacted parts. Ejection properties, such as stripping pressure and sliding pressure, of compacted parts can be improved by using the solid lubricants. The solid lubricants contain functionalized polyalkylene lubricants have the formula: R.sub.1 --Q--R.sub.2 where Q is a linear or branched, polyalkylene containing from about 10 to about 200 carbon atoms, and R.sub.1 and R.sub.2 are each independently a hydroxyl group, a carboxylic acid group or a metal salt thereof, an amine group, a mono- or di-C.sub.1 to C.sub.25 alkyl substituted amine group, or an alkylene oxide group having the formula: --[(CH.sub.2).sub.q O].sub.n H where q is from about 1 to about 7, n is from about 1 to about 100.
