Graphite, hexagonal Boron nitride ( ), Molybdenum disulfide and Tungsten disulfide are examples of materials that can be used as solid lubricants often to very high temperature.   The use of such materials are still restricted by their poor resistance to oxidation (for example, molybdenum disulfide can only be used up to 350C in air, but 1100 in reducing environments).
