机械稳定性是氧化铝的一个重要特性。在从拜耳法厂输送到铝电解厂过程中,特别是在现代工厂中,及干法净化中,不稳定氧化铝容易破碎。其粒径的减小,会引起电解操作困难。实验室研究指出,焙烧方式明显影响氧化铝的强度。因而,本研究的目的是测试来自不同工厂的氧化铝的机械强度,以便找到氧化铝强度与焙烧方式、BET 表面积及氧化铝粒径的关系。在这些实验中应用了改进的 FORSYTHE Mechanical stability is an important feature of alumina. Unstable alumina is easily broken during the transfer from the Bayer plant to the aluminum electrolysis plant, especially in modern plants, and in dry decontamination. The reduction of the particle size will cause the electrolysis operation difficult. Laboratory studies show that the firing method significantly affects the strength of alumina. Thus, the purpose of this study was to test the mechanical strength of alumina from various plants in order to find the relationship between alumina strength and firing pattern, BET surface area and alumina particle size. Improved FORSYTHE was used in these experiments
