Patents by Inventor Eric G. Wilkins

Eric G. Wilkins has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Graphite loaded silicon carbide and methods for making
    Patent number: 7015165
    Abstract: The invention provides exemplary silicon carbide ceramic bodies and processes for making such ceramic bodies. In one embodiment, a raw batch for producing a ceramic body includes a silicon carbide slurry and agglomerates of particles defining a dry lubricant mixture. The mixture includes a binder and a dry lubricant such as graphite, with a majority of the agglomerates having a shape that is generally spherical.
    Type: Grant

  • Processes for making a silicon carbide composition
    Patent number: 6398991
    Abstract: Exemplary silicon carbide ceramic bodies having inclusions therein are produced according to the invention. An exemplary ceramic body includes silicon carbide in major amounts and unreacted particles of an additive in minor amounts which are bonded to the matrix. The particles are dispersed throughout the silicon carbide, and are preferably selected from one or more of the group consisting of boron nitride, aluminum nitride and titanium diboride.
