REFRACTORY CERAMIC COMPOSITE AND METHOD FOR MAKING THE SAME

摘要

PROBLEM TO BE SOLVED: To address dimensional stability and other shortcomings associated with conventional isopipes.

SOLUTION: A fired ceramic article is formed of a composition containing at least 90 mass% of zircon having a multi-modal particle size distribution containing greater than 40 pts.mass of a coarse zircon component having a median particle size of from greater than 3 μm to 25 μm, and less than 30 to 60 pts.mass of a fine zircon component having a median particle size of 3 μm or less.
