Abstract
Owing to their high refractoriness and slag resistance, high-alumina refractories are widely used in the lining of steelmaking furnaces, glass furnaces and cement rotary kilns in high-temperature industries. The impurities in the raw materials react to form the glass phase, which can melt into liquid at high temperatures. The modulus of rupture of refractories depends intensively on the content and composition of the glass phase. In this work, the cold and hot modulus of rupture for high-alumina bricks were investigated by means of fitting based on different theories. The effect of the glass phase on the modulus of rupture was analyzed by combining the phase composition, morphology of fracture surfaces and porosity for high-alumina refractories.
期刊介绍：
The Journal of Ceramic Science and Technology publishes original scientific articles on all topics of ceramic science and technology from all ceramic branches. The focus is on the scientific exploration of the relationships between processing, microstructure and properties of sintered ceramic materials as well as on new processing routes for innovative ceramic materials. The papers may have either theoretical or experimental background. A high quality of publications will be guaranteed by a thorough double blind peer review process.
