Gilsonite in Foundry Sands

In Foundry and Refractories, for molding high value metals there is more attention to factors such as finishing. Gilsonite can be a superior carbon additive replacing the traditional Sea Coal which has low Carbonic value compared to Gilsonite Specifications.

Advantages of Using Gilsonite as an additive in Foundry Sands:

  • High Lustrous Carbon Content to achieve a higher quality on the finishing.
  • Having less chemical reactions between the casting and mold causing less deficiency
  • Significant increase in gas generation comparing to Sea Coal
  • Zista Gilsonite supply for Foundry application have same lustrous carbon content comparing to the American Gilsonite Foundry Grade while the price is also much closer to sea Coal prices which have dropped with the Oil price drop during the past years.
