A fire-resistant grease comprises a fire-resistant base oil and graphitic carbon or oleophilic graphite as a thickener. Suitable base oils include fire-resistant hydraulic fluids, particularly phosphorus acid esters or amides and more particularly trihydrocarbyl phosphates. The graphitic carbon may be of the type described in U.K. Pat. No. 1,252,582 (U.S. Pat. No. 3,532,625) and the oleophilic graphite as described in U.K. Pat. No. 1,168,784 (U.S. Pat. No. 3,384,583). The thickener contact may be 1-20% wt of the grease, preferably 2-10% wt, and the grease may contain conventional additives.
