description	A high-temperature lubricant for the hot processing of metals comprising a mixture of fine-powder materials. To provide a high-temperature lubricant having good trickle and flow characteristics for dissolving scale on heated metal surfaces, which applied in powder form permits good coverage of the metal surface and which even after prolonged storage under production conditions still has good trickle and flow characteristics without severe lump formation and which avoids the use of graphite, in accordance with the invention it is proposed that the mixture includes at least the following constituents (a) a secondary and/or tertiary calcium phosphate compound, (b) a fatty acid or a fatty acid salt, (c) boric acid, a boric acid salt (borate) and/or a mineral containing boric acid salt (borate), and (d) condensed alkali metal phosphates, and wherein the constituents of the mixture have a mean grain size of 150 μm and the lubricant does not contain any addition of graphite.
