  • Patent number: 8011419
    Abstract: Thermal expansion defects, i.e. veining, are reduced in iron, steel, and nonferrous castings by adding a lithia-containing material in a sufficient amount to the silica sand mold. Adjusting current formulations to maximize the use of lesser expensive raw materials and minimize the use of more expensive raw materials to lower the overall percentages of lithia/metallic oxide containing additives while still reducing or eliminating thermal expansion related defects in the metal casting process reduces the overall cost to manufacture the product.
    Type: Grant
    Filed: October 1, 2008
    Date of Patent: September 6, 2011
    Assignee: IGC Technologies, LLC
