The current understanding of the superconductivity of heavy-electron uranium compounds is reviewed. Both the pairing and the mechanism appear to have been established as unusual in UPt3 and UBe13. Small-moment magnetic ordering is now known to coexist with superconductivity in URu2Si2 and UPt3. The understanding of the properties of UBe13 may be viewed as the central problem in heavy-electron physics. © 1988, Elsevier Science Publishers B.V.. All rights reserved.
