- Scope
- This part of GB/T 6609 specifies the determination method for the mass loss of alumina at 300°C and 1000°C. By convention, the mass loss at 300°C is represented by moisture (MOI), and the mass loss at 1000°C is represented by loss on ignition (LOI). This section applies to the determination of mass loss in calcined alumina. The measuring range of mass loss at 300°C: 0.2%~5%; the measuring range of mass loss at 1000°C: 0.1%~2%. This part stipulates that when measuring the MOI and LOI values of samples, the original data of the measurement results should be provided. In order to improve the analytical precision of the sample, the sample should be air-balanced before analysis, and the air balance can significantly affect the measurement results of MOI and LOI. See Appendix A for the steps and effects of air balancing. This section also relates to instrumental analysis methods.
