According to national standard GBZ / T192.4-2007, the pyrophosphate method is the preferred method for determining free silica in dust. The principle of existing solutions is to heat dust with pyrophosphate. While silicates and metal oxides in dust dissolve in the pyrophosphate at 245-250°C, free silica is nearly insoluble in the hot pyrophosphate. This allows for separation of the free silica from other substances through filtration. Finally, the separated free silica is quantitatively measured by weighing to calculate its percentage in the dust.
