A rapid is proposed for the determination of silica in the presence of fluorine. Boric acid is added to the fluorine-containing sample after alkaline fusion and leaching with water. The subsequent treatment may be carried out just as if fluorine were absent. Silica is then precipitated with gelatine solution. The procedure outlined is simple and rapid. So it is especially suitable for technical analyses.
