Method of making cordierite bodies |
摘要 |
In a process of forming cordierite-containing bodies, the water absorption capability or shrinkage of the bodies is controlled using the alumina-yielding ingredients. The process of controlling the water absorption capability or shrinkage includes the steps of providing alumina-yielding ingredients in the form of two aluminas having different particle sizes, wherein the ratio of the two particle sizes is in the range of from about 3:1 to 30:1 or 1:3 to 1:30. Next, a linear relationship between the cordierite-containing body's water absorption capability or shrinkage and the relative percentage of the alumina-yielding ingredients made up by the two aluminas is determined. After determining the linear relationship, a water absorption capability or shrinkage of the cordierite-containing body is selected in accordance with that relationship by adjusting the relative percentages of the two aluminas.
