Ceramically Bonded Alumina And Mullite For Application In Glass Melting Furnaces

The superstructure and regenerators of glass melting furnaces are both critical areas where silica and standard magnesia, as well as fused cast materials, are used. Over the past years, disadvantages of these materials have been observed, causing the glass industry to look for other alternative refractories, such as ceramically bonded pure alumina brick. This article presents both laboratory and in-service results of the materials based on fused corundum and fused mullite that are subsequently sintered at high temperatures for the final brick production.
