one α- Al203 content: α- Al2O3 content reflects the roasting degree of alumina. The higher the calcination degree is, the higher the a-Al2O3 content is, and the hygroscopicity of alumina becomes worse with the increase of a-Al2O3 content.
2. Particle size: mainly refers to its thickness. The particle size must be appropriate. If it is too coarse, it will cause slow dissolution and even precipitation in the electrolyte; If you pass the rules, you will easily fail.
3. Wear coefficient: the so-called wear coefficient refers to the percentage of particle size change in the sample after alumina is worn and collided on the fluidized bed under certain conditions. Wear coefficient is a physical index to characterize the strength of alumina.
4. Angle of repose: refers to the angle of inclination formed by the natural accumulation of materials on a smooth plane. Alumina with large angle of repose is easy to dissolve in the electrolyte and can well cover the electrolyte shell in the electrolysis process, with small flying loss.
5. Unit weight: refers to the mass per unit volume of the material in the natural state. Generally speaking, alumina with low bulk density is conducive to dissolution in electrolyte.
6. Wear coefficient: the so-called wear coefficient is the change percentage of particle size content in the sample after alumina is worn and collided on the fluidized bed under certain conditions. Wear coefficient is a physical index to characterize the strength of alumina.
