ABSTRACT:
A solid lubricating material consisting essentially of an intimate mixture of about 15 to 50 mole percent molybdenum trioxide, balance molybdenum disulfide. This material is particularly useful under extreme environmental conditions such as very high temperature or vacuum. The material may be used in powder form, compacted into a pellet or other desired shape, incorporated into a grease composition or incorporated into a resin-bonded solid film lubricant.
