P roduct I ntroduction Natural flake micropowder graphite is a kind of nonmetal mineral, It has characteristic of good high temperature resistance, oxidation resistance, corrosion resistance, thermal shock resistance, high strength, good toughness, high self-wetting strength, good thermal and electrical conductivity and other unique physical and chemical properties.

Ultrasonic Leaching of Urania

The proposed use of unclad, urania-impregnated graphite fuel elements in experimental and power reactors raised the question of how best to reprocess the elements after irradiation. A grind-leach process using boiling nitric acid was previously suggested as alternate to earlier combustion techniques. Besides requiring pre-grinding of the elements the process did not leave a residue

Carbon/Graphite for Dry Running Mechanical Seal

Graphite grains are the key to carbon/graphite's self-lubricating ability. Thus, by increasing the graphite content in a seal face, its dry running abilities can be augmented. Carbon/graphite manufacturers are able to do this using a process called graphitization.
