A Volumetric Method for the Determination of Silica in Glass, Sand, and Silicate Materials

JSGT 1956 V40 T509-T512

 
A method has been developed for the determination of silica in glasses, sands, and refractories, by precipitation of potassium silico-fluoride followed by alkalimetric titration of the precipitate. Starting with the ground and dried sample, the total time for carrying out duplicate determinations is less than three hours. Apart from its general use for speeding up silica determinations, it is completely applicable to fluorine containing glasses.
