  • Patent number: 9666854
    Abstract: A graphite powder may include highly oriented grain aggregates, wherein the electrical resistivity of the powder decreases with increasing density. A process for coating a substrate may include providing a coating dispersion including such a graphite powder and applying the coating dispersion to the substrate. An electrode may contain such a graphite powder. A coating dispersion may include such a graphite powder dispersed in a liquid medium. A battery may include such a graphite powder. A compressed body of pure graphite may include such a graphite powder. A lubricant may include such as graphite powder.

  • Patent number: 9527740
    Abstract: The present disclosure relates to ground expanded graphite agglomerate compositions, methods for making such agglomerates, their use as conductive additives, and conductive composites including such ground expanded graphite agglomerates. The disclosure also relates to methods for making such composites and the use of such composites in preparing thermally conductive materials. The agglomerates may be characterized by a certain softness allowing the agglomerates to dissolve, for example, through shear forces applied during compounding, thereby leading to an improved feedability and a highly homogenous distribution of the expanded graphite material in the composite matrix.

  • Patent number: 9212083
    Abstract: A system and method for coating glass gobs with a liquid-based lubricating dispersion during their drop to blank glass container molds which provides sufficient lubrication to the glass container molds without requiring swabbing of the glass container molds. The lubricating dispersion is sprayed onto hot glass gobs as they fall from the gob supply system prior to their distribution by the gob distribution system into blank molds. The lubricating dispersion coats the falling glass gobs to lubricate the glass gobs as well as the molds.

  • Patent number: 9102539
    Abstract: The disclosure relates to processes for the production and thermal treatment of carbon material, in particular, graphite powders, in an Acheson type oven, using a functional filler comprising graphitic material in particulate form allowing electrical current to flow through the charge. The particulate form of the filler allows greater flexibility and can be used to control the degree of direct and indirect heating, resulting in more uniform products. Such graphite materials may typically be employed as an additive in polymers, batteries, or other applications.
