GB/T 5195.8-2006 Fluorspar—Determination of silicon dioxide content
Abstract
This standard specifies the principles, reagents, samples, analysis steps, result calculation, and allowable deviations for determining the silica content in fluorite. This standard includes three methods: the molybdenum blue spectrophotometry, with a determination range (mass fraction) of 0.10% to 2.00%; the gravimetric method, with a determination range (mass fraction) of 1.50% to 40.00%; and the reduced molybdenum blue spectrophotometry, with a determination range (mass fraction) of 0.05% to 4.00%. This standard is applicable to the determination of the silica content in fluorite.
