    摘要: A solid, self lubricating bearing material especially useful as a sliding electrical contact in vacuum environments comprising a high temperature lubricant chosen from AlPO.sub.4, BaF.sub.2, CaF.sub.2 and mixtures thereof, a lower temperature solid lubricant chosen from the chalcogenides which exhibit lubricity, & a silver matrix, the ratio of high temperature lubricant to silver being about 1:4 to 1:10, the ratio of lower temperature lubricant to silver being about 1:2 to 1:8. Filler materials up to 20% by weight chosen from aluminum oxide, silicon nitride, molybdenum silicide, metals from Group 8 of the Periodic Table, and mixtures thereof may be added to alter the hardness of the material.
