GB/T 6609.25-2023 "Chemical analysis methods and physical property determination of alumina - Part 25: Determination of bulk density and tap density" is applicable to the determination of bulk density and tap density of powder materials such as industrial alumina and activated alumina (excluding nano-sized alumina). It specifies the test principle, instruments, procedures, and requirements for result calculation. The test requires the use of a 100mL cylindrical measuring cylinder, a specialized funnel with a 6mm aperture, a tapping apparatus with an amplitude of 2mm and a frequency of 300 times/min, and an analytical balance with a sensitivity of 0.1mg. After sample pretreatment, standardized filling or tapping operations, and weighing, the two density values are calculated, providing a basis for optimizing alumina molding processes and controlling product quality.
