CASTING MOLD OF GRADING WITH SILICON CARBIDE |
| 摘要 |
The disclosure relates generally to mold compositions and methods of molding and the articles so molded. More specifically, the disclosure relates to a mold for casting a titanium-containing article, comprising calcium aluminate and silicon carbide, wherein said silicon carbide is graded in said mold such that it is in different portions of the mold in different amounts, with the highest concentration of silicon carbide being located between a bulk of the mold and a surface of the mold that opens to a mold cavity. |

1. A mold for casting a titanium-containing article, comprising:
calcium monoaluminate, calcium dialuminate, mayenite, and silicon carbide, wherein a concentration of said silicon carbide in the mold is graded such that it is in different portions of the mold in different concentrations, with a highest concentration of the silicon carbide is proximate a facecoat of the mold, wherein said facecoat is located between a bulk of the mold and an interior surface of the mold that opens to a mold cavity. |
