Scope

WARNING: Personnel using this standard should have practical experience in formal laboratory work. This standard does not address all possible safety issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This standard specifies the principle, reagents, samples, analysis steps, result calculation and tolerance of the method for determining the content of silica in fluorite. This standard includes three methods: molybdenum blue spectrophotometry, measuring range (mass fraction): 0.10% to 2.00%; gravimetric method, measuring range (mass fraction): 1.50% to 40.00%; reduced molybdenum blue spectrophotometry, Measuring range (mass fraction): 0.05% to 4.00%. This standard applies to the determination of silica content in fluorite.
