Due to different resources, the standards of different countries are not completely consistent. For example, in European countries, the lower limit of Al₂O₃ content for high alumina refractories is 42%. In China, Al₂O₃ content in high alumina brick is generally divided into three grades: Grade I - Al₂O₃ content > 75%; grade II - Al₂O₃ content is 60-75%; grade III - Al₂O₃ content is 48-60%.
