Les briques à haute teneur en alumine sont un type de matériau réfractaire, et le composant principal de cette brique réfractaire est Al2O3.
If the Al2O3 content is higher than 90%, it is called corundum brick. Due to different resources, national standards are not completely consistent. For example, European countries have set a minimum Al2O3 content of 42% for high alumina refractory materials. In China, the Al2O3 content in high alumina bricks is usually divided into three classes: Class I - Al2O3 content>75 % ; Classe II - La teneur en Al2O3 est de 60-75 % ; Grade III - La teneur en Al2O3 est de 48-60 pour cent.
