GB/T 6609.37-2009
AbolishedChemical analysis methods and determination of physical performance of alumina - Part 37: Determination of the particles size content less then 20μm
氧化铝化学分析方法和物理性能测定方法 第37部分：粒度小于20μm颗粒含量的测定
Application Summary AI generated
This standard specifies the method for determining the content of particles smaller than 20 micrometers in alumina, typically using laser diffraction or sedimentation techniques. It is applied in the aluminum smelting industry and by alumina producers to control raw material quality, as fine particle content affects the handling, dissolution rate, and emissions during electrolytic reduction. The method is also used in quality assurance and procurement specifications for metallurgical-grade alumina.
