| 摘要 |
The present invention includes a method for producing high-alumina bodies with superior chemical properties at reduced sintering temperatures. One form of the method includes the steps of providing an alumina powder precursor, adding about 2 wt. % magnesia powder precursor and about 2 wt. % titania powder precursor, mixing the resultant green powder precursor, pressing a green body from the green powder precursor, removing residual moisture and organic material from the green body, and firing the green body to about cone 13. The resulting high-alumina body has a substantially uniformly sized grain structure, is resistant to dissolution in molten aluminium, and has superior resistance to chemical attack over substantially the entire pH range.
