The high-temperature lubricant for the hot-working of metals which comprises (a) 10 to 90 percent by weight of graphite, (b) 2 to 45 percent by weight of an alkylene homopolymer or copolymer, and (c) 0.5 to 8 percent by weight of a dispersing agent. The lubricant is solid at room temperature. The high-temperature lubricant is applied in the form of an aqueous solution which includes 5 to 80 percent by weight of the solid high-temperature lubricant. The process of production and use of the high-temperature lubricant. The high-temperature lubricant for the hot-working of metals which comprises (a) 35 to 90 percent by weight of graphite, (b) 2 to 60 percent by weight of an alkylene homopolymer or copolymer, (c) 0.2 to 8 percent by weight of an auxiliary suspension agent, and (d) 2 to 40 percent by weight of a film stabilizer. The lubricant is applied in the form of an aqueous solution which includes 5 to 80 percent by weight of solid lubricant. The lubricant is used at temperatures of around 900.degree. C. or higher.
