Abstract: The copper rhenate (Cu(Re₄)₂) was prepared using chemical method, and its thermal stability was analysed by TGA(Thermogravimetric Analysis). The lubricating behavior of the copper rhenate at elevated temperatures were determined under three rubbing pairs (Al₂O₃/Glass, Al₂O₃/Stainless steel and Glass/Glass) by means of high temperature pin on disc tester. The results show that the copper rhenate dehydrates at 80～150℃, decomposes from 510 to 730℃, and has a good lubricating property between room temperature and 700℃, especially from 450 to 600℃, in which its friction coefficient is about 0.15. Under the rubbing pairs of Al₂O₃/stainless steel, the copper rhenate possesses long term lubricating role at high-tem peratures.
