A microporous graphite foam, comprising a matrix of graphite fibers joined by a graphitized graphite-forming precursor, wherein the foam comprises irregular interstitial spaces having an average pore size in the range from about 0.1 to about 10 microns and a void fraction in the range from about 80% to about 95%. A process for producing a microporous graphite foam including a matrix of graphite fibers joined by a graphitized graphite-forming precursor. In its various embodiments, the graphite foam has one or more of pore sizes less than about ten microns, low bulk density, high physical strength and good machinability, while also having the desirable characteristics of graphite, including high thermal conductivity, electrical conductivity and solderability. A cryogenic cooling system including the graphite foam. In one embodiment, the graphite foam is a component of a cooling interface in the cryogenic cooling system.
