Abstract: A composition for lubricating and/or descaling in the hot processing of metals includes a solid mixture containing the following constituents: (a) 20 to 60% by weight of condensed alkali phosphate, (b) 10 to 40% by weight boron compound selected from borosilicate glass, boric acid, boric acid salt, or a mixture thereof, (c) 10 to 30% by weight alkali or alkaline earth sulphates, (d) 5 to 25% by weight fatty acid, fatty acid salt, or a mixture thereof. The sum of the constituents (a) and (b) constitutes at least 50% by weight of the mixture and the sum of the constituents (a) to (d) constitutes at least 85% by weight of the mixture.

Abstract: A lubricant for the hot forming of metals, with respect to the solid constituents, contains at least the following constituents: 55 to 85 wt % of a solid lubricating agent comprising a mixture of talc and a potassium mica, wherein the ratio of talc to potassium mica in the solid lubricating agent is 2.0 to 5.0, 10 to 30 wt % of an adhesive agent selected from a polyvinyl acetate, sodium water glass and dextrin or a mixture of same, 2 to 10 wt % of a thickener selected from hydroxy cellulose, hydroxyethyl cellulose, hydroxyproply cellulose, carboxymethyl cellulose, methyl cellulose, ethyl cellulose, methylethyl cellulose, hydroxyethylmethyl cellulose, hydroxypropylmethyl cellulose, ethylhydroxymethyl cellulose, carboxymethylhydroxy cellulose, dextrin, starch, organically modified bentonite, smectite and xanthan gum, 0 to 10 wt % of further auxiliary agents, and not more than 10 wt % of graphite.
