Na K Ca Mg Fe Cl Pb
Acid Insoluble
97.0 0.03 0.01 0.02 0.005 0.001 1.5 0.03 0.002 0.05
NOTE: Li2SO4H2O content shall be obtained through the calculation of Li content.
3.2 Appearance Quality
Products shall be white crystalline particles and have certain fluidity. There shall be no
visible foreign inclusions.
Along the center of a sack, insert the sampling tube into 2/3 area of the sack. After
mixing up the sample, use quartering method to divide the sample to around 200 g.
