Research in the Field of Preparing Molded and Unmolded Refractories Based on High-Alumina HCBS. Part 8. Effect of Firing Temperature on Properties of Materials Based on Mixed HCBS Composition: Bauxite, Quartz Glass, and Reactive Alumina1

详细

The effect of firing temperature on shrinkage or growth indices, porosity, and ultimate strength in bending is studied in specimens prepared from bauxite HCBS, and also additionally containing reactive alumina CTC-30. For all material compositions there are typical preferred sintering temperature ranges (900 – 1200°C) with prevalent mullitization accompanied by an increase (1200 – 1400°C) in sintering or shrinkage of mullitized material (1400 – 1600°C).
